Working with them for many years, affiliate program is not for beginners and extremely sh*tty, so affiliate program scams for every sneeze. In general I can recommend it, as the conversion is really better than many affiliate program in this area, but I drive traffic in the plus, it is better to have your own site, spam and pushes. In other cases, especially with purchases there is a big chance to go into minus, or here you have to know how to work with the motive.
