I know this won't even be hardly seen, so I'll be quick here. Yes, I know about the exclude tagline for the url. No, it is not a suitable replacement for a NOT logical tag.
You guys have been online for over 10 years now, and are one of the lead indie hosting websites, in fact for those of us who frequent and (I don't want to understate this) ABSOLUTELY LOVE your website, we all hate to see this site be looked at poorly. But personally I would never spend a dollar here, and will recommend friends do the same on this site singlehandedly because of stuff like this.
We're not mocking you, and this shouldn't be rocket science, but negative filters are important for any person who uses your site, almost nobody only wants to see one kind of game, and almost nobody doesn't dislike at least one.
But yeah, I figure this is gonna get some nothing response or just get deleted immediately, I just thought it was important to keep bringing it up that we aren't gonna shut up until you guys eventually do it, or somebody else does it better.
