I couldn't post for three-four days, I prepared a message for the web admin, but I could not contact him because I got blocked at the contact form too. This was the message, because I got two different types of error:
=====
Good afternoon mr,
Got this message while trying to post to the forums: "There is suspicious activity from your continent and you can only continue with the webmaster's assistance -- contact him or her immediately"
I couldn't post yesterday neither, but I got a different message. something about enabling JavaScript on my browser (although it was enabled, I even reinstalled my Firefox browser)
I cannot contact the webmaster because I do not find a way to do so (the contact form, also neglects me from posting).
======
The worst part of it was that I lost the ability to contact anyone on Cmon, even the webmaster, so I could not tell anyone that I can't contact.
The better part is that I can post now, so I suppose the problem is completely solved.
