"xxxnovel.wetandmessy.com" is a correct title of this game. I thought that this tag helped a wider search. In addition, "wam" is an abbreviation of "wet and messy". These two tags may be confused. Therefore, I think that it is inappropriate that you changed the tag of this post. In addition, it is not suitable that you removed "wam" from post 258079. Because that "wam" means "wet and messy" simply.
Not on Danbooru, it doesn't. Stop making so many tags. Pick one tag and stick to it. No wam_(copyright), no wam_(game), no wam. Just wam_xxxnovel.wetandmessy.com, if that's what it's called. If there's ever confusion, it will be dealt with much later when it actually comes up. I don't think anyone cares enough about this game anyway.
