What about add a banner that service's admin can add in their thread? I think something like this for now:
http://puu.sh/gs6Sd/523fb30aa3.pngService's admin can add the banner in the main thread of the service and users can monitor the status. With this, admin can give users more trust and people can instantly see if that service is SCAM.
The admin that don't approve this banner (maybe, but not sure) are scammers and don't want to promote the banner because this thread alert that his service is SCAM. For the next days some service will enable this banner and we can see after some days/week the services that don't insert the banner in their thread.
Tell me what you think about it.
I like the idea, although maybe a signature is better for the service providers? Then it's displayed on all of their posts.
