I have a very simple and I think, useful approach when it comes to Skype addresses. There are a number of BST threads where the owner of thread has listed his Skype address and there appears to be multiple versions of the same, or similar, address in Skype's system. Some of these addresses are users who are trying to scam people by purporting to be the original, legitimate seller from here. Sometimes they will use identical avatars, which makes it very difficult to see who is the real person and who is the copycat. Example of this would be: blackhatworld live:blackhatworld blackhatworlds If you were to search for blackhatworld in Skype, all three would appear. One could be the real seller on here, but the others could be scammers. Now one thing I've never understood is when a BST thread owner is aware that there is a copycat that is using a similar Skype address to scam people, why do they not change their Skype address? Not only are they losing sales, but they are allowing other people to be scammed. I really struggle to get my head around this. I am also quite incredulous in this regard as I do not think that every case involves a copycat scammer. I even had one user who claimed there was a copycat person scamming people with a similar Skype, but both he and the 'scammer' shared the same Neteller email address. So, I have two suggestions to avoid this scenario: 1) All Skype addresses posted in the opening sales post should use the 'Contact Me' creation tool (https://www.skype.com/en/developer/create-contactme-buttons/). I believe this uses basic HTML and would be supported on the forum. I've tested this tool and as long as you put in the correct Skype address in the first place, it will mean a conversation only opens to that address. 2) If it becomes apparent there are people being scammed by a copycat Skype account, then the BST admin/mods should require the thread owner to change their Skype address.
