Lockerz.....Legit or scam???

I joined Lockerz a couple of months back but I haven't earned enough PTZ to redeem anything there. I've seen proofs that Lockerz is not scam and that they have received the prizes they chose to redeem. I guess the spams in the email is due to the fact that before, Lockerz was an invitation-only site and you have to ask someone who's already a member to send you an invitation. I guess that's where the spamming starts as there may be some who's taking advantage of the huge amount of email addresses that come from the invitation requests. I'm just making a wild guess here.

Doing some math in your mind proves lockerz is almost scam. They used to give free t-shirts for everyone who refers 20 users to the website and that's true. And many says they've got stuff from Lockerz (especially in the beginning). Lockerz doesn't have much income stream (may be their daily questions are sponsored!!) so when they say "We're restocking" I guess what their restocking would be a dozen iPhone stickers, 5 t-shirts and 2 iPhone,one iMac. I've earned 2000 points there and they're giving huge amount of points for watching videos, logging in, answering etc. and the point is that - those points are "USELESS" I redeem that points to an iPod touch I must be before the computer for a completely unannounced 1 hour prize redemption which normally happens a midnight of the last week of the month. And their SHOP which currently allows US only is of no use for me either. AND FINALLY THE MOST IMPORTANT THING: these points which I'm stacking up in my account since there is no way for me to spend is going to expire within ONE YEAR!!

its half a scam and half not.. if you are tryin to earn points for their special redemption FORGET IT! they run out immediately after it stars and tells you right when it starts.. if you earn points to use to shop through them its legit because you can get stuff for free if you have enough points and i and my husband have gotten dvds, games, clothes etc from it.. no spam as far as i know
