I can go on for days but I'm bored. If you really believe he's not a future scammer and needs to be tagged with negative feedback then idk what to tell you.
All I ask is a member from the default trust list and if they feel he is a scam threat to mark him. I already have him on ignore. I presented the information and its your call if you feel hes a risk or not.
Please don't misinterpret what I initially told you... I agreed he's probably is - but told you that your case couldn't be validated at that time. NOTE: these posts are AFTER your initial OP. I reviewed his post history and didn't find anything relating to what you claimed... it's possible he could've deleted them before anyone got a chance to see them. Point is, none of that was linked to your claim against this member. Trust me - when I said it looked like you were just angry because he didn't pay up - that's what it looked like for lots of people I'm sure.
Sure, I consider this behavior suspect... most would probably agree. But again - NONE of that was posted! I'm pretty sure your request to tag his ass will happen soon - if it hasn't already.
