I have been banned?

[Grimes]

Hello, sometimes when I come to FK it says I am banned and there is no reason? Happened already +5 times. I visited this site maybe half year ago when I didn't got accout here yet and it said I was banned.
Also today when I visited here it said I was banned. I dont know is this a bug or something but I just wanted to ask.

That's due to the anti-spammer plugin. Bans your session from a suspicious ip or proxy.
