I joined this site Zen Zuu. Do anyone know if it is a scam?  

Try to google it and see what people are saying about it. You should just write zen zuu scam and the google search will give you everything you need to know about this website. Se if they have some kind of a forum. If they don`t they might try to hide something and don`t want their members to discuss it in a forum. You should also see how much they give per click and how many you can click a day. Usually legit ones only give 0.01 cent per click and offer between 4 to 8 a day.

If something seems too good to be true, it generally is. Put "Zenzuu.com scam" into Google and see what comes up. It seems to have been around since 2008 but few are being exactly enthusiastic about it (and those that are posted a while ago, when it was new).

Let's face it, MySpace, Facebook and Orkut just about have the "social networking" scene sewed up, so newcomers like this are not going to attract the members - therefore the advertising revenue - to make them more than just a fringe site, if that.

I think you should know how to checking whether a site is legit or not already. Some comments above are good and you may try them. I myself never heard about this site before. But if a site is legit and many people received payment from them then you can easily find some evidence about the legitimacy. However, a paid social site usually ask for more effort from us in order to be able to earn more money from such site. Have a nice day and happy mylotting.
