I have noticed this, and have missed most of the tournaments I've signed up for recently because of it. I've become quite disgusted with this site of late.
In fact, the other day I cashed in a tournament, and withdrew nearly all the money I had out of their site (because of my frustrations with them). The very next day I received an e-mail from Poker Host's SECURITY department. Before I opened the e-mail, I was QUITE CONCERNED! My first thought was maybe someone had hacked into my account? When I opened the e-mail (I wish I kept it; I would have included what they typed here), they asked me why I had decided to withdraw nearly all the money I presently had in my account with them. I told them there was no specific reason for my having done so, and that I would most likely re-deposit again in the very near future. This was OF COURSE a lie, and I have no plans whatsoever to deposit now or anytime in the future at their site. That's not to say I won't play freerolls there. And in fact, I'll take any money I win in those tournaments and cash it out immediately as well (including our tournament coming up on the 17th).
