I became member of clixsense two months ago and my experience is not what I was expecting before joining it.
I think I am just wasting my time and effort I am putting every day clicking on available advts for 0.001$ and even getting 4-6 advt only per day. They just got banned from Paypal which says a lot.
If you want to advertise there- dont bother, no one pays attention to the ads, only to the timer. And even with 5 seconds timer most sites wont even load. You cant complain in their forum. At first I thought Clixsense was a really good site, received hundreds of paid ads a day, but now it reduced to 5-6 ads only.
When I questioned this I was told that most of the ads are going to paid subscribers. According to me, unless they can credit faster, on average, its not worth waiting an entire months time to decide the fate of your credit.
I find it interesting that the ads slowed down when I close to cash out, also when attempting to do tasks you are redirected to CrowdFlower and then can not access the site. Clixsense customer service is of no help concerning this issue.
So, overall not a safe site, will close account and not return.
