You can ban him. There is an "ignore" button. I visit this forum maybe twice a month to see what's going on and had never heard about this person (or so I thought.) Lo and behold, they were already on my ignore list.
On your list already, funny how that worked out. I wish more people would start using the ignore button instead of grabbing their pick axes and torches for a good old fashion ban hunt.
We all know how easy it is to persuade noobs. Tell them anything and they'll believe it, heck there are still people who are 100% convinced when they receive an email from the prince of Nigeria in their spam folder, a lot of the time there is nothing you can say or do to stop them from falling for it. Thats why obvious FUD campaigns need to be removed. I don't think fallling needs a ban though. We should bring back the colored ignore buttons though whereby the more ignores you have the darker the color of your ignore button. I don't know why that was ever removed.
