Thanks for sharing this, I did not know there was such a feature. I do a lot of online selling and buying of different items, what I have found with scammers is, They usually will always have a story of some kind!" And......usually it is a hard luck story, or has something to do with either being deployed out of the country, or a family member is deployed or in some way compromised.I just reported a different user - literally within the last hour or so - by using the "Report" button on one of their posts - I got a response from Len - he watches the activity from the "Report" function.
Good luck - yes - buyer beware
