Both of you are forum users, do you exchanged any forum PM each other? From where you get the receiving address? If it's on telegram then just forget about it. If the deal has done off-forum, then nothing to do with forum users. If someone uses my profile link in any campaign and uses his own telegram username and somehow you get a scam from telegram then you can't blame me really.

You should write more about how and why you get scam and the most important question is why not use forum PM that you are dealing with a real person. So at least you would have valid evidence against the scammer and we may punish him. Currently, we can't tag without proper evidence.
