So I just attempted a member search to see if there are any other members with a username similar to mine. I tried several combinations but nothing pulled up an option other than my own actual username.
I will again state that I believe LHPanther's publicly posted phone number was the weak link here, I'm afraid. I'm a long-time member on several other forums including SnipersHide, and it's a common problem for someone to say "I'll take it" in a thread, and a scammer will then reach out to the prospective buyer before the real seller does. To combat this, it's become common practice for the buyer to initiate contact with the seller via PM first, THEN post in the ad. That, or buyers should only trust communication from the seller in a PM chain that THEY initiated.
It may be that LHP doesn't have enough forum activity to have access to PMs, which would aggravate this issue, but putting your phone number out in public invites these kinds of problems. I'm not sure what I'd need to do to clear my name, but I'm happy to do whatever is needed. Maybe Len or another mod could PM us both. I could provide my phone number and would be happy to have a phone call (or even video chat, as my face will match my avatar), and then they could ask LHP what phone number the scammer used to see if they match? I don't know. All I know is my word and reputation mean everything to me online as that's what my ability to buy/sell rides on.
