Restrict usage until someone approve it. But this is a stupid idea because it requires people to put their time and computer on the line to approve something what also could do something hidden.
Like you test an app and it seems to be clear and not a scam, and later on community crys because they lost stuff.. No i wouldnt do that.
Yeh, I don't want to over-complicate the site and its administration. The admins, GMODs and MODs volunteer their time (and I greatly appreciate the effort), but it's really pretty simple to run the site because it's so hands off for me and others. But when it starts sounds like "a job" is when I start to lose interest.
We'll figure something out.
