How to identify spammers/bots at a glipmse

[Hall of Famer]

Well many of you have seen me banning users immediately after they registered, and you may wonder how I can identify them as spammers/spambots. The trick is quite simple, look at their profile and 'About me' Tab. Every user whose sitename is '123456' are spambots from Russia or East European countries, it is actually quite astounding to me. But anyway, if you identify any other users qualified as spammers/bots but have yet to be banned, post in this thread and I will take care of them soon.

I noticed that they all had the same sitename, I thought it was just to fill space XD
