Exact same name on HF (the HF profile was actually created first):

All of his posts on HF:

As you can see most of them are blackhat related: E-Whoring, RATs, Botnets.

I'd also like to note he was posting this:
http://www.sythe.org/private-server-gold-items-misc/1852081-giving-away-ikov-auth-bot-free.html
And there were concerns that it was infected. The bot wasn't leaked at this time as far as I know so it's unlikely he would've been giving out the bot for free, and he was more than likely trying to infect Sythe users, which is probably why he didn't post any download link publicly so people couldn't scan it. Lines up with his RAT interest from HF as well.
