Telegram Scam Bot Exposed by Fixed Timer and Deleted Messages in Telethon Userbot Analysis
A detailed investigation into a romance scam attempt on Telegram revealed an AI-driven userbot masquerading as a woman named Maria from Yaroslavl. The bot maintained consistent 4-5 minute response delays regardless of message length or time of day, responded to deleted messages, and accumulated multiple inputs before replying in batches. It refused out-of-character requests using repetitive phrases like "I am not a..." and handed off media or confusing inputs to a human operator. The bot failed to react to a nonexistent city name and ignored voice messages containing silence, leading to delayed human intervention. The chat was later deleted from the scammer side after testing, and the account ignored messages from a second profile. The analysis includes a full reconstruction of the bot's logic using the Telethon library, highlighting prompt protections against jailbreaks and reliance on fixed delays.
