I didn't remove your posts (and I've absolutely no idea who has done). My best guess though is that someone either decided that your post was a moan about the moderators (which never goes down well with us!) or that it was simply 'inappropriate for Chatterbank'. I've removed quite a few posts for that second reason recently, including from regular and much-valued members (such as Jennyjoan). However, even though I think that the Ed's Blog might have been a better place for your posts, I wouldn't have zapped them in CB for that reason myself.
We've always had 100+ spam posts per day. If they're staying in 'Latest Posts' for a little bit longer than usual, it just means that there aren't that many moderators around at that particular time.
