It gets on my nerves when there's a full system set up so that you can publicize your deals in a specified, highlighted section and people ignore it and just post their ads in global chat over and over. I don't see why they're still allowed if we have a specified method for in-game advertising. Perhaps not all ads would be banned - typical "Buying/selling (item) /msg me" could remain, as they only exist until the item is sold and take the conversation directly to private chat. The problem lies in people advertising, say, their shop using a copy-pasted phrase as many times as is possible without raising a mod's eyebrows. When everyone does this, virtually nobody uses ad credits save for the occasional "(player) is dumb lol" or "Go to /kitpvp". This trains people to ignore the ads and makes global chat ads just as effective as ones using an ad credit and in any case it makes the purchase of said credits far less appealing due to their lacking impact and I could imagine that's not the intended result of any item a player can buy with hard cash. In my eyes, the point of the system is to take ads off of normal chat and put them into a separate (and far more noticeable) section, and not to offer a tiny to nil advantage over those not willing to pay.
