LDL and I were typing almost simultaneously, but my response was posted a few minutes later. Certainly, there isn't enough evidence, but it's not that there isn't any proof regarding LDL and the conducted transaction; this doesn't seem like a coincidence to me. Why would someone try to ruin his reputation, while the Telegram messages show a great similarity with how LDL is writing? Another user is claiming that it's an attempt by someone on their local board to defame him and another user, but there's no proof of that. How do we know that it's not a network of scammers blaming each other and then proceeding to say that they've been framed? Why would someone who's trying to frame LDL send money to his wallet, since it can easily be returned? He could impersonate him in plenty of other ways.

I'm not sure, but the whole situation seems sketchy enough, and no evidence is easy to discover. The OP should at least receive his money back and turn this into a valuable lesson.
