Maybe you reblog them super often and they don’t want their notes cluttered by only seeing you? Or it was an accidental block when they looked at your blog?

Well, no, I didn’t reblog them often actually. Basically I only used to reblog their posts when I saw them in the dwedit tag and similar tags – I’m not even sure I was following them before they blocked me tbh, but I surely know them for their great gifsets. It could have been accidental but apparently quite a few non anti-moffat blogs have been blocked so I think it’s unlikely. 

Not a big deal tho, I just liked to reblog their original content and automatically try to do so whenever I see their posts, but then I get the error message and i’m like “oh yeah… right… whatever”. That’s all.
