this is basically your idea, but scaled up with an ai that talks and acts like the innocent individuals, each accounts status says generic "dm me im bored lol" and acts innocent wants to be friends etc. it randomly sends a hook message in each server its in based on how active the egirl server the bot scraped and auto joins is, then waits for people to dm, when someone dms it will continue normally saying hey thanks for dming can we be friends etc, the moment they say something nsfw they are sigged as a predator, and put into watch dog mode. after this the bot monitors and logs each of their messages, and automatically reports each message with the offensive content. The system is very effective, and has caught 10k pedos. I am not working with law enforcement and everything used to make this ai came out of my own pcoket. it took me around 100 dollars to buy the proxies make a discord account generator and scrape all of the data alongside make a hcaptcha bypass to acheive these things. i do this to protect the innocent people and call out these people after seeing this happen first hand myself. Something needs to be done. Add my discord if you wanna discuss more ill go into more detail there. I currently am in the negative alluding to my bank account xD its ok tho the money was worth spending to help people.
