we need to contact his social media to confirm if he's want to sell account. Anyone can post like that and using someone social media, this is why we need to confirm.
That was some honest effort put in by @coolcryptovator, but as suggested in that thread, users should not make it a habit of messaging members off the forum in search of evidence. This could easily turn into a circle of accusations as we had
here.
Screenshots from telegram are not really worth much and you would need to provide proof by getting the suspected seller to message you from the account profile on bitcointalk, this PM would also need to be verified by mods or some high ranking member; Mods would hardly intervene in these cases especially when it involves private messages, the latter would require you giving up your details and then changing them, some users may not be comfortable with that.
There would also be the possibility of you getting involved in a triangle, where a user is communicating with two profiles in sync, and requests one to send a message to the other which they claim to own. Of course no one would send "I am selling my account...", But a more benign message such as "I messaged you on telegram *inserts screenshot*" could pass undetected.
You also risk getting yoursl social handles reported by the suspected seller.
My conclusion, that is too much trouble to go through to fish out sales and it's a pain to verify for other members.
