Has Onbux turned scam?

It is not just you the site has been having problems for about one month and I just answered this to another discussion view it here: http://www.mylot.com/w/discussions/2501521.aspx

only problam i c is will lose money as have too meny rented referal so will loose big time if the site not come in some time

As others have asked previously, Onbux is not scam (yet). They are completely legit and still paying but they do have a larger downtime than other websites. I don't know why exactly they are offline so often but they have always come back online/active and they will this time as well. You just need to be patient. As you can imagine, there are many people using the website and it could be that they are doing maintenance works, their bandwidth limit for this week has been reached and exceeded or they just have temporary server issues. But as the past has shown, there is no reason to worry.
