My hobby is to choose a random Redditor or Twitter user and find every intricate detail about their life I can. I'll spend multiple days going through their posts, cross-referencing their usernames in other sites and try google haxxing to find documents in their name. I don't actaully do anything with this information, I just like to have it. On rare occasions I like to email everything I have on them (name, addresses, names of family, phone # etc.) through Tor and a burner mail, with a guide on OPSEC and instructions to delete information off the internet. Then I delete the info on my hard drive because I'm not actually interested anymore by this point.
