I can't get my Hubski account activated. What's going on?

I’ve emailed the admin and haven’t gotten a response in the last 4 days. I can’t post and I can’t comment (under comments it says “account not activated”, along with “click on email activation link to participate” if I hover my cursor over it) I’ve also sent them a PM. Should I just wait longer for a response? Am I on some sort of black list? Are the admins being lazy and are not maintaining the site? What’s going on? This is on hubski.com.
