Clan boards are a privilege and are expected to have the same level of post quality as the rest of the forums. Spamming your post count up to enlarge your epeen is not a good use of them. When I went through and purged the spam threads, I read a few pages. If it was just random spam, I deleted it.
I have no problem with offtopic threads, it's only when the majority of the posts are one word or there is hella spam that there is a problem.
