I do not think it is a scam. It pays me regularly, however it pays far below the amount I should be getting (according to its own metrics). I am looking for somewhere else to move my 1,000 - 10,000 clicks per day.
instead of posting here, have you contacted their support yet about this problem ?
Yes of course. The only reason I posted here at all was because I got no answer from support.
Also if there is a problem then posting here will be helpful to others.
When I checked the site today, it appears my balance has been reduced to zero! (I only had about 0.06 or something in there I think, as I withdrew everything else a few days ago).
Definitely something up with the service at the moment, it isn't running as it should.
