Uh did you not look at this users profile before dealing with him.
There is nothing but red remarks from alot of reputable users already.
That should of been a clear sign to stay away from dealing with them.
I'm new and do not know the question of how to check it. Because he is a senior member and a small amount was made a quick negotiation. To be hard to find reliable Skrill negotiators here in the forum.
I deal with skrill and have regular trades with another user on a weekly basis.
You just need to ask around to get a good trader that's all.
But if it is in anything other than USD currency I can not help you there. The fees are just too high for currency exchanges within their accounts.
