My point is that many hosts like you and deeplist would likely not have joined if you would not have been allowed to post ads for your host. Let's say 10 % of those who join to post ads end up later participating in other forum discussions. It's like when a grocery store has a sale on some item to lure customers in to buy other things. Most will not buy other things, but some of them will. That's the basic idea. As an incentive for web hosts to join.
