It sounds to good to be true... $10 per pay-per-click and up to $100 to read emails!! It really, really does sound too good to be true! And that's because it probably is one of the worst scams I've ever come across on the net.
Please, please, never-ever-ever join this site, but if you do feel the need to test it out, don't waste your money on the $20 upgrade.
A minimum amount of $75 000 must be reached for payout, unless you upgrade to a Gold Member, and then there is no minimum payout. But you will be waiting a minimum of 30 days for payout, and possibly longer, but you'll never know.
Quote from the website FAQ itslef:
"All payment requests made in the current month are processed within 30 days of the following month with upgraded members being the very first to be paid. Sometimes under certain circumstances of a lot of payment requests you may have to wait a reasonably time longer. When such unfortunates occur we usually send our members out a free gift. No matter how long it takes all members will be paid according to our terms of service."
And this quote from the Terms of Service on the site
"Giga-Mails has the right, in its sole discretion, to suspend or cancel, at any time and for any reason, a members membership in and access to Giga-Mails website and Giga-Mails sevices. All Earnings may be cancelled in Giga-Mails sole discretion."
So not only could you be waiting an indefinite period of time for your payout, but Giga-Mail can, if they don't feel like paying you, cancel your earnings or your account. For any reason at all.
YOU WILL NEVER GET ANY MONEY FROM THIS SITE. Simple.
