Still cannot post in the Buy Sell Area of Domains?

Been here for a little while now, doing my best to help out a lot of people, today ran into a few problems, particularly with one poster who seemed bent on trouble and a mod who seemed very trigger happy at deleting threads with no explanations given to lots of people, besides that, have enjoyed my time here.

However, still not able to make new threads in the Domain Buy and Sell area.

Why would this be please?

If you look at my posting history, you'll see that at least 95%+ of my posts if not more, have been helping other people, yet still I cannot access certain areas of this forum.

What gives?
