Back Posts are disappearing

I posted a few replies but they disappeared. Why

If all this site is - is for wholesalers to drive by and pimp their brokerage - with their full email address website URL - in their signature - and no one else is - retail agent or otherwise... This forum will remain the dead zone. I agree that straight up drive by advertising is lame - but if someone contributes a fair amount of content on the topic/thread at hand - why does their signature get whacked off the post?

"It is not intended as a free advertising vehicle to promote members' services and products." Sure thing ... See a lot of wholesalers and Cluster Agency Managers "advertising" their services and products yet - not a single banner ad on your site from them. It is what it is ... whatever ...
