That's not parody. Parody is not simply trying to be funny. This is why Weird Al actually goes out and gets permission to do the songs he does, because despite the popular thought, most of what he does isn't parody. Parody requires that the new work is used in such a way to comment on the original. Replacing a few words or singing something in a funny voice isn't parody in itself. Depending on how the account is being run it may not be parody either. As time goes on, it's easy for people to misunderstand things, like those "in soviet russia" jokes.. it wasn't simply a matter of swapping two things, the jokes were used in a way, with specific things to comment on the government. Nowadays people just swap something in there with no thought and it doesn't make sense.
Likewise people simply think "If I draw something funny, or make a stupid version of the name, it's fine I can do whatever I want". That's not true.
