Spammer Leonid "Leo" Aleksandorovich Kuvayev has been imprisoned in Russia on multiple child molestation charges.

"Sources in the United States and Russia said that Kuvayev, who holds dual Russian-American citizenship, was alleged to have molested more than 50 young girls he had lured away from one or more local orphanages," writes Krebs on Security's Brian Krebs. "He was brought in for questioning after one of the girls reported the incident to Russian police, who reportedly found videotaped evidence of the incidents."

"Kuvayev is widely considered one of the world’s most notorious spammers," Krebs writes. "Anti-spam group Spamhaus.org currently features Kuvayev as #2 on its Top 10 Worst Spammers list."
