Links in these e-mails usually led to some pharmacy shop, which paid Tolstokozhev a share of its revenue. This is a well known affiliate scheme employed by spammers worldwide. Tolstokozhev is estimated to be responsible for up to 30% percent of all viagra and penis enlargement related spam.In order to send millions and millions of unsolicited letters, Tolstokozhev employed a network of infected computers (so-called "botnet"), which he rented from hackers.How profitable is spam? Well, the authorities say that Tolstokozhev has likely made more than $2 million in 2007 alone. (in comparison: average russian monthly salary is $400)
