True, and as others have pointed out the flip side of the lack of a gatekeeper in fanfic is the lack of a warning structure on profic. :)

It makes me tired. Every time something brings an issue like this to the fore (or, in some fandoms, every time the seasons turn) someone brings up the same argument like it's Brand New, "See?? This is why you should change your ways." And in the end it's never new, there are people on one side asserting their expectations of behaviour of people on the other side.
