I have started testing it with one reasonable domain, not too much traffic, making about $100/year, travel oriented. I was skeptical at first when I saw all local UK ad links, but then some good click were seen and the performance looked better than the annual average. If I recall right, I did not spot good clicks lately.

I have attempted to try them also with an adult domain, but that did not work at all. One could not pass the barrier of the opening minors protecting pop-up which would reload rapidly whether you click YES or NO. Didn't bother to complain since such an obvious defect they would have to notice of their own.

I have checked how many domains do they host or park, at

Today I see number 1162, 5 weeks ago it was 206. So, they are really a start-up, and one needs to be cautious.

By the way, another start-up, EVOlanding, parks apparently 4100 domains (data updated two weeks ago).
