If your report in the Russian section didn't work, then try or did you try to report these spammers in Moderators using "Report to Moderators" button. Maybe it'll work. At massive spammers like this, it is really hard to take actions unless Moderators just nuke their posts and ban them. But eventually, these spamming won't end by just banning them over and over again. People uses their brains now properly and they can still find a way to repeat spamming with new accounts.
Spam is already like a never-ending flow of water in a river that won't easily stopped by just blocking with stones. It's already part of the forum. It's sad that Bitcointalk reached this kind of unstoppable situation.
