My IP is blacklisted

[Yooh]

As title said, this is what written when I want to post something (I'm using proxy right now):

Your IP 58.65.245.234 has been blocked because it is blacklisted. For details please see http://www.spamhaus.org/query/bl?ip=58.65.245.234.

I don't have this problem before, when I posted several post and played already. I have scanned my laptop but resulted nothing. I have no idea if my boarding house's internet resulted in this or not, I can't contact the owner, and not for this problem. Well, of course I'm not the owner of spambot or something malicious.

I have read other topic like :
viewtopic.php?f=8&t=59961
viewtopic.php?f=8&t=64804
But still, is there something I can do to fix this? Or maybe can MS Administrator fix this?

Thanks for advance.

Fixed by its own please

Edit : Oh, yes

Edit again : Or if any administrator fixed it, thanks

Ahoy, thanks for telling me! Will avoid proxy if the problem occurs again.
