Why is the profile private? Also, could you please post proof on this topic, preferably in the OP. Make sure it is from the desktop app. But even then it could still easily be photo-shopped. Steam accounts can also be easily taken back by steam support. I don't recommend buying them, especially from a low ranked member like OP who has nothing to lose by scamming.
Just made it public and posted other proofs.
Regarding the low rank and the risk of being scammed, I will accept to be paid after the buyer has received the login info and verified the account, but this is reserved only to hi ranked users.
