How to make sure whether a site really pays or not?

visit my blog in my profile to see sites that pays me already. my blog also list many ways of making money online

How? Research the site from other forums, check them on whois, ask some reliable members who have joined that site already, after you've got some positive feedback then Try it! just don't invest. Why? Payments proofs can easily be manipulated, people are just posting proofs to get more members. We should not be fooled by any proofs any stories of success. It's really easy to provide such.

i do not think with out seen any payment proof you can trust these sites because it is very difficult to reach at minimau pay out so maximum do not reach there and leave the site with frustration and they do not really know whether site is paying or not

Ys, I agree with you. There are so many sites that does not really pay its members. Well, I think there is no particular way to know whether a site really pays or not unless you experience it yourself. There might be some people who say that they have been paid by there are some that say that they have not been paid by the same site. SAd but true.

I don't mean to say this, but all of the answers to your question are wrong. All legit paying sites should have a monitor paying tag attached to it. A paying tag is a banner with a link to an unbiased paying site monitor where members of the paying site can vote on its preformence. If you want an example of what this looks like please check my profile banner #2. Thats our paying tag. Monitor sites keep people in the know of a programs statis. Also a good thing to look for is forums. NON-SITE forums. The reason why I say non-site is because if a site is a possible scam then they can doctor their forums. One word of advice though. There are many scam monitor sites out there as well. The most notorious is maxhyip, anything with MMG attached to it, investtitles & investden. I hope this helps you out.
