The forum account can be hacked and unfortunately you were targeted. If you both or the Trio (You, OG and Burky155) were using signed bitcoin address to communicate with each others using current date then I think this sort of damaged could be avoided.

Whatever you do; the idea is, the important information should be digitally signed from known bitcoin address. So you do not need to trust the forum account or telegram account or any account.

I am wondering why OG and minerjones or anyone else who are offering their escrow service do not practice digitally secured signing.
