Aren't demotivators techncially against rules?
At least those that aren't original artwork of creator, but some art used without permission, and, what is important, source of artwork was obfuscated this way.
I can imagine that whole thing was created from start to end by same person , but it's rare (only example I can think of, probably, is original "bear cavalry" one, although there were copycats and mods of that).
As well as they often bear some offensive, disparating or contraverse "public message".
I think, their place is somewhere on 4chan , not at fandom site.
