Coming from the receiving end of this. As a user of a anonymous image board this happen recently. It seems that hola is selling botnet access. Of course users are "vetted" that they are not going to use the access for nefarious purposes before they gain access. In this case one of the "vetted" users decided to DDOS said anonymous image board. (Note:Could be some other actors involved, but have confirmation from other board users).
