The bots found my alt account. One commented on my Ultra Moon gameplay journal (which you should totally check out!), and then another bot with the same account name (but with a different number in the username) commented on my Pokémon Randomness book. Both bots mentioned the exact same instagram profile. I still think it's funny how they say "oh, I loved the story and the characters so much in your book" on my stories that have no characters and no plot line. This is precisely why the internet was invented. 

At this point I'm just responding to them with "Fuck off bot" and blocking them. A small part of me feels bad for saying something so rude to what could possibly be an actual person, but I'm fairly certain it isn't an actual human leaving these comments.
