Banned for spam?

My account was banned for spam. My last post was in General Discussion where I replied to a person being blocked from accessing parts of the unity website by his antivirus. I posted stating it’s best to remove his antivirus and stick with the stock windows protection. I then replied to him again after he posted stating that if he still needed a good firewall that was free then he could head over to the TinyWall website and install that free firewall. I linked to it in my post.

Today I try to come to the forum and it states I’ve been banned for spam.
