Maybe the reviewer doesnt speak english and runs his replies through a translator... he typed in "I'm sorry but we don't accept those type of sites here" and it gave him "Don't submit your shit here!" lol I think its a translation service UW set up
On a serious note although this isnt the case here I find that people who don't speak english often seem very abrupt and it can be taken the wrong way too easily.
In this case it seems to be just an asshole that I will not put on my submit list.
