This is correct half the time..The other half is like this:
1- Register free Account
2- Login to Your Account
3- Press claim
4- Write the correct captcha
5- Get An error occurred: Server is busy , please try it in an hour again!
6- Complain on Bitcointalk.org
7- Stress because you don't know if the site has scammed you, and will you even get ROI
8- A few hours, or maybe a day or two later, admin finally posts that site is ok now
9- You are able to withdraw your accumulated balance of hundreds of thousands satoshi!
Unfortunately right now I am on number 6 and moving to step 7
