Gab admin is a major scammer. He hasn't paid after four weeks and keeps telling me to wait.
 I wanted to buy advertising for Adbuxpro, but he didn't approve it. 
Stay away from this scam site.

As far as I remember (I have stop using that website long time ago, becouse the earings was too low and it consume too much of my time) waiting period for free members there was 30 days or 30 business day (not sure which).

Now I can see in their TOS that they have added several rules for cashing out:

"

1. The Maximum Withdraw Limit for all members is 150% of your deposit + OfferWall Earnings.
2. If you haven't made a deposit, you can withdraw up to $3 + OfferWall Earnings.
3. Standard users must have at least $1.50 in OfferWall earnings in order to be able to withdraw.
4. Payments are processed manually, after a detailed review of your account.

Payout Schedule: Standard Members, will receive: Regular payments, which take a few weeks to process."

I did everything you wrote there, even wrote to the admin, who just lied and lied.
 What I found outrageous was that I wasn't allowed to buy advertising for this site;
 he refused, probably because he doesn't like honest sites, this scammer.
