To be fair, not everyone knows what sites are banned from being posted or even mentioned. A lot of people don't partake in website wars. I know I personally visit multiple sites, and I'm friends with people who work at other sites despite working at the "Site that Shall Not Be Named" (it's a bit extreme you can't even type out the acronym imo, but I don't know the story behind the ban nor do I really care to learn it since there's no changing it I'm sure). Same goes for a lot of my coworkers and people who work at other sites. I know some people take the competition very seriously and will ban mention of certain sites (the Disney World subreddit has banned so many sites, including the one I work for, for reasons as petty as posting rumors despite putting "RUMOR" in all caps in the title and reiterating that what the article is talking about is a rumor. The site also banned Mickey Views not too long ago for the same reason iirc.)
