Beside reading reviews from members of the site, i also read several blog or sites who share their experience about using the site and also i believe it when my friend suggest me to join because they have proof of paymentWhen joining a site, the first thing i check is usually the customer reviews. Once i have gone through the reviews of the members on the site, if okay with it, the next thing i check for is payment proof. After seeing all this before i decide if it's legit or not.
