The behavior of each of your guild members represents the guild itself. With poor behavior, with posts that get deleted from this forum, you get a very poor reflection of the sort of quality you have. If you want good members, you have to weed out the bad. If you want to be a good guild (in terms of quality) then you have to make sure you maintain a strong image.
If one member acts like a five-year-old in public and you're actually promoting him, that tells everyone here a lot about the sort of guild you are running. What it tells me personally is that you are incapable of being a strong leader, nor having strong officers beneath you to help you out. If you are here to just goof around, this forum section isn't for you.
