I think Registration is now needed in order to post is just an UNDERSTATEMENT.
Spammers have gone too far, I close a previous post as quick as I can. I was on guest mode at that time.
This spammer, "germundiulus", went out and post some content not intended for the business environment. Just remove this person and block any traces from this spammer.
I suggest that there be a harsher regulation like email confirmation, some monitoring program that goes in depth to look into the other outside information of the "spammers" in case they want to get back in, and if to the max restrict and even ban the spammers for posting anything from any site that includes such content.
