I too have complained in my blog about the scammers and the negative image it creates for the site, it is something that definitely needs to be addressed. This is readily apparent no matter how long you have been a member.

At the end of the day this is just a website - the only thing it really serves to do is to act as a platform for communication. Theft is a 'Real World' issue - one that needs to be deal with in the proper manner - ie - with police. The police have the correct tools to deal with see more these things - tools commonly referred to as the law. Account suspension is not the right way.

It is not Boonex's responsibility to act on hearsay - they would be foolish to do so, I do think that it would be a good move to suspend / remove accounts for members that have proven to be acting illegally on / via the site - but this would obviously require proof of a conviction or a trust in the person making the accusations, at the end of the day is only a courtesy - not a requirement (unless forced by court injuction).

I have been in a similar situation on a site that I run, where a vendor had been accused of taking orders but not delivering - it was a difficult situation to deal with. I ended up suspending the account and removing advertisements - this was largely based on the fact that I could trust the accusers opinion, and that there were several reports.

I will say that this situation is actually a LOT more difficult to deal with here - mostly because of the melodrama associated with the accusations - it reminds me of the boy who cried wolf - There's too much background noise to be able to distinguish fact from fiction.

ZenTens answer a few posts down is very eloquently put, and echo's my thought's on this.

Just out of interest, are you talking from personal experience when you are mentioning theft?
