Our admins have communicated the situation with support on numerous occasions lately, through multiple channels. And search is optimized for exact matches. I simply searched for your game's name. That would be while logged in, by the way; NSFW games definitely don't show up otherwise. And that's why I suggested double-checking your tags. They're probably not the best selection.
As for why your game's traffic dropped so suddenly, you said it yourself: that happened when you marked it as NSFW. Makes sense, really, since a lot of people can't see such games at all. It can't be helped.
