i believe it would be best if any scammer just says clearly that he wants to scam.
the forum could have a checkbox like "only show non-scammer threads" which hides the scammers.
hint: trust ratings are easily abused
Yeah, that would be the best option, and set a fat clear SCAMMER tag above they'r heads if you do choose to show them, so you won't make horrible mistakes
So , I go around offering a few microloans , end up with a couple of trust points and then I can insta-ban someone from the Lending forum ?
This will give huge power. The trust system is a guideline , not a true indicator as trust can be bought quite easily
