I work with them relatively recently, but I already have an idea about it. I've tried to work in the affiliate marketing, but it is more stable to collect pushes on downloading traffic (torrents, videos). For splits with other affiliate programs I get higher profit if I use fresh traffic. I had some questions about code, but thanks to the support, they've sorted it out. It is clear, that as in any affiliate program, there are it's pros and cons, but on the whole everything is ok.
As for the wishes: growth of the advertisers base (more competition for my traffic) and tickets for important events in the admin panel will also be useful.
