Best of luck to you then, I can only advise against it. Been around WoW long enough to see the ins and outs to know its not worth it.
If I could make a recommendation to you, try smaller platforms like discord servers or even twitter for advertisement. The WoW forums are pretty much trade chat or reddit these days. I mean…its always been bad, but over the years its become particularly meme’y.
