I've personally added "@@http://*.battlemaster.org/*" to my AdBlock+ settings so that I can turn on the ads and they'll actually show up. I don't know how long I'll keep them there, but for now the small text box is perfect for me.
I'm glad to see something like this; I have wanted to support BattleMaster, but I don't really have all that much extra cash (because I don't want to be a jerk and just donate a single Euro), and I don't use the fourth character slot I have now. I'll have to make sure to occasionally click one of the ads so that it actually makes some revenue :p
