They've Started Hogging Up My Notifications So It's Getting Kinda Annoying - Tumblr Posts

I'm confused by the sudden increase of followers without pfps? And it seems that a lot of them are related to JJK in the sense that their following list mostly consist of the same list of JJK artist blogs..

I'm inclined to think that they're bots and so i just wanted to put it out there, if you've got no personalisation on your blog, i'm going to assume that it's a bot and block you :/
