RTM control's their ability to communicate/post on other people's journals and in some cases lock them out from seeing valuable journals. Give them just enough to prove their interest, intelligence, and commitment for several months. Then, at your discretion, they can be offered entry into the whole website.
I doubt a troll or a thief will spend months posting on a site without showing their true colors....
I'm not sure if this would work, but it might be a good way to find skilled traders who otherwise wouldn't join due to lack of ability to pay.
I know for a fact some of the best traders on RTM come from abused countries. It is exciting to see them empowered.
