Doesn't post his skype but the person he's trading with does. Googling his skype volkoffhttp comes up with several blackhat related results such as this post where he's offering to teach people how to run a shop with cracked accounts:

Also what seems to be his HF profile by the same name as his skype.

-87 Rep for repeated accounts of sketchiness, selling databases he took from other people, etc.

HF stopped loading for me after so can't take screenies of his posts right now..

Also seems to be a ban evader given his IP match with this banned user (only IP of the other user):
