I had gotten my invite from Graet all I did was send him a pm asking for one.  Though I do intend to use not only for Hashpower but I'm waiting a little for the Canadian market to pick up before trying it out.

So far I'm happy with the service and it's on par with Gpumax.  I don't really see the sensationalizing, alarmist talk about these services.  I've pointed my BFL Single crunching away at 800mhash/s and honestly as a miner I do not in any way shape or form care where my hashes go.  On this site you are limited to what mining pools you can set your worker to so it isn't like I'm selling off my power for some nefarious purpose.  I've mined on most of these pools at some point in the past and just switch around on a whim.  Why not bitch and complain about abcpool? Isn't that the same idea? Or what about people who purchase shares just off of the forum? Why aren't you giving gigavps shit?

Don't get me wrong, I support Bitcoin but I also go where the money is.
