I decided to add cpmfun back to my site, so far so good, ads loading very well not seeing any problem, no popups no adfly so far, we will see how everything goes. After all their cpm rate is very good, and we all know that's very hard to find now days.. Will keep everyone updated, please share your experience here! PS. Yes I have already been paid 2 times by cpmfun, they are not a scam network however they did have major problems with popups and adfly that's why I had to remove them last month.
