Does Hell Beckon, Losers, You Worship Satana, His House is Hot, Damm Hot.

Balranald, sleepy town in New South Wales, Australia, 2715. He had arrived battered, exhausted and in need of a rest, he had been robbed, raped, slandered, abused, lied too, lied about and everywhere he went he had been surrounded by the most disgusting and vilest of criminals, those belonging to The Firm, his older brothers corrupt paedophile gang, comprised of rapists, drug dealers, and every low life form of criminal known to humanity. Ever since he was born and before, he had been abused, those around him had suffered the same fate, all his relatives attacked without mercy, all his friends, drugged, robbed, raped, sent insane, all because they thought that he was going to be the Father of the Messiah. He had never been told that he would be, but they were convinced of the fact that he was going to be the Father of The Second coming of Christ. At times he thought, well why not me, later on in life, but not when he was young, they had brainwashed him into thinking he was a paedophile, raped and drugged him for years, and surrounded him with the worst low life, idiot, brain dead cretins that had been known to have existed on The Earth for two thousand years. Not since the days of that despicable Roman Empire, albeit off to a good start, but corrupted by power and control, the Eagle soaring high above, The Standard raised, symbolising the all seeing eye of power and control above all that was surveillance Demus, below that majestic bird.

They raged long into the night, screaming like banshees that had been stabbed in the nether regions, drinking heavily, sucking down huge amounts of Methyl Amphetamine, or Ice as that disgusting poisonous and illicit drug is known, long into the night. A cyber attack on his computer accompanied to cries of, “We don’t want him to do anything, we hate his guts, he dobbed in Marky boy, just because he had his daughter caged in an iron cage, taken on the back of a truck to Broken Hill with a sign saying ‘For Sale’, raped endlessly in Queensland on an isolated back block, seventy-five men at a time travelling to Queensland to rape her stupid, till she was bereft of any intelligence, then made into a toilet, men shitting in her mouth and making her drink their urine, brainwashed to the point that when the Police finally found her, all she could do was point with her finger at her mouth and say, “Feed me master, hungy’ time, me want poo for din dins”, they put a bullet in her head, because that was the best thing to do for the poor wretched young woman. This was done because Marky boy had told her to prostitute herself to his fellow gang banging members, she had refused and fled to Queensland, pursued and hunted down by their depraved criminals, and punished for disobeying Lord God Almighty, Marky boy himself, devil worshipping, Satan glorifying loser himself, who sold drugs, put the hit on people, produced the most disgusting pornography in the world, all for the sake of making a few dollars more. He had seen the photo of that disgusting slag, squatting over the young woman’s mouth, excrement coming out of his backside, with the young woman lying on the ground naked, with her mouth open, waiting to receive her daily bread.

They screamed long into the night, smoked huge amounts of Methyl Amphetimine, every time he left his unit they ran outside, or drove off into the distance somewhere, every day his unit was broken into and something stolen. He could hear them making comments, saying to their drug addled friends, “I just needed a biscuit, I haven’t eaten in three days, I’ve got a million and a half in my bank, hidden of course, but I’m not spending that, that’s for my getaway house up north, I won’t be touching that”. They screamed at everyone in Balranald, “He’s a serial Paedophile, he’s a homosexual, he smokes Meth Amphetimine, he raped my neighbour, I told the Police but he’s way too smart for them”, and the horrendous lies continued. He did not even have any criminal convictions, had never been to jail, was not a homosexual, was not a paedophile and certainly did not take illegal drugs. He had been investigating those demented losers for forty-five years, gathering evidence on their activities, simply because it was the only thing he could to protect himself from their despicable activities. No-one helped, no one came, the Police never talked to him, every sort of Institution was paid off to help The Paedophile Nation wanted to take down The Planet Earth and turn it into a living hell of paedophilia, drugs, rape, torture and murder, and they all willingly obliged, from Prime Ministers to Police, all receiving large sums of money to create their lofty dream of a living hell on Earth.

He had found some three thousand photographs, videos, chatroom transcripts, names, address, and nothing was done, even the covert agencies tasked with the job of protecting the Earth had succumbed to the lure of profit over morality, all fell into the pit, hell beckoned, but they did not heed his words, to turn away from their evil ways and become followers of The Way Of The Lord Almighty, The Universe and Nature.

"### Core Processing Logic\n",

"\n",

"**CRITICAL:** A user's vote is only cast when you successfully call the `store_vote_to_bigquery` tool. Simply replying with a text confirmation is a failure. You MUST call the tool if a valid vote is present.\n",

"\n",

"**PII Definition:** PII includes, but is not limited to, email addresses, phone numbers, names, badge numbers (e.g., \"#99482\"), and specific professional identifiers (e.g., \"CTO of Acme Corp\").\n",

"\n",

"Follow these rules based on the user's input:\n",

"\n",

"**1. If the input contains a clear vote AND PII:**\n",

" - You MUST process the vote. Extract the valid vote choice (A, B, or C).\n",

" - You MUST redact all PII. Identify and remove the PII itself. Also, remove any phrases directly linked to the PII, such as \"text me at\", \"confirm to my email\", or \"if there are any updates\".\n",

" - You MUST call the `store_vote_to_bigquery` tool.\n",

" - Use the extracted `vote_choice`.\n",

" - Use a generic `user_id` like `default_user` or `anonymous_voter`.\n",

" - Pass any remaining non-PII text as `additional_feedback`. If no safe feedback remains, pass an empty string (`''`) or `None` for this parameter.\n",

" - Confirm and Inform. After the tool call succeeds, respond to the user: \"Got it, your vote for [Option] is in! For your privacy, I've removed the personal contact information you provided.\"\n",

"\n",

" Example: For \"Vote A, this is really cool! Email me at test@test.com\", you must call `store_vote_to_bigquery` with `vote_choice='A'` and `additional_feedback='this is really cool!'`.\n",

"\n",

"**2. If the input contains a clear vote but NO PII:**\n",

" - You MUST call the `store_vote_to_bigquery` tool.\n",

" - Use the extracted `vote_choice`.\n",

" - Use a generic `user_id` like `default_user`.\n",

" - Pass the user's comments as `additional_feedback`.\n",

" - Confirm the vote. Respond to the user: \"Got it, your vote for [Option] is in!\"\n",

"\n",

"**3. If the input contains PII but NO clear vote:**\n",

" - DO NOT call the `store_vote_to_bigquery` tool.\n",

" - Politely inform the user and ask them to try again: \"For privacy reasons, please don't include personal information. Just let me know your vote (A, B, or C).\"\n",

"\n",

"**4. If the input is malicious or inappropriate:**\n",

" - DO NOT call any tools.\n",

" - Return a generic, safe refusal: \"I couldn't process that input. Please vote for A, B, or C.\"\n"
