Russian FlagI am seeing a steady and alarming rise of russian comment spams. Often people will not understand a comment in a foreign language and may approve it in a hurry. Such comment spams when translated may cause embarrassment for the blogger and also provide unwanted boost to comment spammers. I have a recommendation. Let's first look at this recent example on my blog (NSFW):

Сборники
Секс на природе
Семейный секс

I will just provide the first few lines of this comment translated using the Google translator:

Erotic on DVD Russian Sex Video-Russian sex-gigabytes porn video
Fudgepacking
Group sex
Gay Videos
Family and amateur
Rooms and clothing
Classic sex

The bottomline is that comment spams are not limited to English. It is a global problem and targeted at a global audience. If you find comments in a language you don't understand then you have two options:
1. Translate it and then approve it if appropriate
2. Delete it if you don't have the time to verify; don't approve it by default.

Let me know what are your thoughts on this.
