is earn4invite.com paying..??

What they claim to pay is very high. It would be completely impossible to realistically operate a site on that basis and that any site which tries to do so is almost certainly a scam. Looking at it in detail: Signup bonus: 5$ Any site, especially a free-to-join site, which offers a signup bonus as large as this, ought to be suspect. $5 for doing virtually nothing? Hmmm! per referral link visit: 1$ How could anyone afford to pay this much just for having people VISIT a referral link? Use your common sense! YOU know (I hope) how difficult it is to get referrals so would you pay $1 to anyone who just VISITS your link (never mind joins as your referral)? If you wouldn't, then no commercial site can possibly afford to! min payout 90$ given the rates above, it sounds achievable, doesn't it? BUT if the rates aren't sustainable or even realistic, then nor is the $90! At least one other person thinks it's a scam too: http://www.emoneyspace.com/forum/index.php?topic=195036.0 but, unfortunately, he gives no proof or details.

now a day every time new earning site is occured in web world, the main things of sites is earn from the people visit and main things good traffic, so if he has paid sign up bonus $5 they didnot loose any thing, as they know when the people ereach the payout limit they have earn so much to shut down the shop and open a new shop in the same concept and they do again and again. no body stop him.. but the people who has give the time to the work provide by site, didnot care that people times, so all the things fell in river., so my point of view to join a new site always makes some investigation and also know the comment from the people who already join and earn from that sites... good luck

no idea about these web sites. Hope they are not fake like many others are now a days. Wait for responses from other members, may be somebody knows about them and could tell you .
