Stopping the troll
I hate to say this but, it is time to stop the madness with the name change and troll business. The member that is doing this is doing nothing but degrading this excellent site. The member actually does occasionally post beneficial questions/answers and comments but all the other bs just makes people stop coming to the site.
I understand that you can block a member, don't read a persons post but really with the name changes you would constantly be blocking this person as they change names. I don't know if the owner should band this member or what but something needs to be done. Just my 2 cents.
