Tumblr’s hella shit, my dude. I suggest seeing if either of them peeps block you, and if that’s not it try refreshing your wifi/data connection. If neither of those are the issue hmu and I’ll rereblog it for ya. If that doesn’t work, tumblr’s just being a douche.
It’s not letting me reblog it from literally anyone which is bizarre. I dunno how to see if I’ve been blocked but I probably have been. Ah well -shrug-
