No-Minimum Sites. Worth It?

I think it's safe to say that there are no PaidToClick sites which give $0,01/click AND have a $0 Minimum Payout... There ARE however other "Paid To" Sites which have no minimum payout.
Not all of them are reliable and a lot of them spam the hell out of you. I think the best two 'no-minimum' sites are: Donkeymails and No-minimum. Best way to earn money with these is either getting a lot of referrals of course, or by doing the Sign Up ads. A lot of them ask for Credit-Card information. NEVER Give out information about your credit-card! Only sign up at the sites which only need non-personal information. Fake the info if you need to. (Don't tell anyone I told you that! xD) These no-minimum sites are great for getting some quick money which you can cash out fast when you need to.
Guidelines for these kind of sites and other unreliable sites:
1. Never give out valuable personal information. Especially your Credit-Card number.
2. Use a 'spam e-mail'. Which is an e-mail adress you use when you expect spam or use to register to sites where you only need to use your e-mail to register. This way you can save your regular e-mail for friends and other important stuff! Everyone needs one!
3. Carefully read things through! You don't want unexpected stuff to happen!
4. When Signing Up, You might be asked if you want e-mail to your site inbox, your e-mail or both. ALWAYS check Site Inbox ONLY. Or you'll get spammed to death on your e-mail account. Even on a spam-email its annoying.

Anyways, good luck! and watch out with what you do!
