I'm on tumblr, so yes, I know that. However, I also know that tumblr has shithuge hordes of teenagers who have a habit of reblogging shit and joining in on mobs without questioning if they're being lied to AT ALL if the message being passed around seems like it's fighting for a good cause. They may be well-meaning, but they join in anyway.
There's so much shit, so many blatant lies, so much harmful misinformation and full-on bullying being passed around as "important omg" or such. So fucking much, it's depressing. A huge part of tumblrites just do not understand fact-checking. At all.
It's a problem.
