SCAMMERS. They sell invalid traffic! They themselves wind up the botnet, because normal publishers have not been working with them for a long time, they only throw them away. In no case do not buy traffic from them, Google Adsense has long been their botnet detect and ban, and your account will be banned as well. My account was not banned, but the income was cut off because I have a good relationship with Adsense. I was written that more than 1,000 publishers have suffered because of Propelleruds. After my complaint to them, they hastily blocked my account, along with the money and stopped answering. No money, no traffic.
