Real issue - too many actually have no idea at all, BUT they THINK they do - and willfully do not want to know more than what they already do, and also do not what any part of the tiny bit they think they know, but are wrong - corrected at all.
Now this is not quite as big of a problem as it once was - but it is still a pretty big one!
I myself was harassed for quite some time on another forum (a HUGE one) over that same issue (funny it was only one, and I never made any attempt to hide that - showed up right in the public profile - along with programming groups, Linux OS, Server configuration, ex.). But that ONE a** just plain did not want to leave me alone about it. (Mind you I hadn't had any communication with that guy at all before he started - must have been looking at profiles, or posts in certain "groups", ex.).
HOWEVER, eventually people from the "Normal" groups found out that guy was hassling me, and some of them let him know, they did not like it much (btw attempting to explain I was IC, and have been my whole life, only seemed to make matters worse!
That was definitely a big violation of their TOS - but I didn't report it (I know I should have - basically just got stuck on an attempt to make him see just how wrong he actually was), but eventually someone from the programming group did - UNFORTUNATELY that just made that guy VERY angry - SWORE I reported him!
But eventually, a mod put an end to it - took a long time, but eventually... What a nightmare in the mean time though!
