At any given time there can be 200 requests in the approval queue. I know I am lazy so it's easiest to just hit spam clean all lol. Sorry if you were a casualty
The very same thing happened to me. I contacted one of the moderators and he cleared it right up.I joined, introduced myself, and posted some pictures of my bike - I got banned for spam. I wrote the forum and the ban was lifted saying sometimes the forum filters are a little too aggressive. Now that I am back my posts are being moderated for approval before being seen - takes a long time.
LoL, I have never felt so welcome!
