Well, with the new rule, you cannot sell scammed items, and it would be a good time to implement this to get rid of all nasty stuff on MMOwned. We should purge the Trading Forums, and use a system like other forums. Something like this (first is lowest form of security, if you want to keep adding steps you can, but it can get extreme, which might not be needed):
1. In order to get your service posted, PM an Admin your thread, the Admin/Mod/etc. will say its appropriate, and the thread gets approval.
2. In addition to 1, you could say that mods get a free review of the service, product, to deem it appropriate.
3. This is a bit extreme, but to weed out the bad, unreliable, scammers, etc. you could charge a fee to post a service, etc. Only for some big things.
Just to make the services reliable and good choices, also to keep scammers, etc. out.
