Keep in mind AP does expire, Aeria will revoke it if you don't use it, they already yanked 50 AP from my account:
"201211297599576 2012-11-29 18:56:25 Exhausted AP 50" <=wtf?
also don't trust the free AP things from Supersonic Ads, they have one on there for "mega flix" where they want you to enter a cc (to test this i snagged a walmart pre paid card, purchased cash shop currency for 3 different games 2 other publishers just to make sure the card would work.) to create an account to get 650 AP. It says in fine print "We will not charge your card for creating an account" seems promising right? well they were correct they won't charge your card cause they don't exist... mega flix is a scam site, Hard when you click the offer it redirects you to about 6 different masked domains randomly. If you try to inquire about it, supersonic ads just says "we didn't get any verification from the advertiser, so you didn't complete the offer"
I also did 2 other ones from Matomy some super mario halloween one and draw something, both required an installation of some nonsense program, after actually playing both games, screen shotting them both on my browser, the nonsense program installed (Virtual Machined it, never trust that crap I've seen them slip through sandboxie) on my start menu. Also got denied, AP when inquiring about it. I already reported the supersonic ads issue to Aeria support, they say they don't have anything to do with them, but if they didn't they wouldn't advertise getting Free AP via those ads.
If you want to get AP just buy it, or do the real small like survey/videos or w/e if you really want to sit through them, any AP offer that has over 100 AP is a full out scam.
