From much experience as both a moderator and administrator, and as an ordinary poster, in fora dating back many years, may I caution people about feeding trolls.
A troll is a person who adopts a persona, whose only only motive is to disrupt a forum and cause grief and upset amongst its members. Often they appear, at first, to be genuine, but their actions soon reveal their real interest.
They usually target fora that have a good record of peaceful, considerate interaction amongst their members, like this one. Their wish is to get good contributing members to leave. Don't let them force you away.
Anything said that is not directly focussed upon their own ego, or nay sayers, are immediately targeted for ad hominem attacks. Like the ones we have seen recently.
The best course of action IMHO is not to reply to them at all, even to give them good advice or to challenge their point of view. Experience tells me that when they aren't fed at all they go to seek new pastures in which to feed upon others.
The next thing to do is to add the individual to your "ignore list" which means you won't see their posts any more.
I have already added a recent joiner to my ignore list. This person displays all the characteristics of being a troll, IMO.
And if that person attempts to respond, tough, I won't see any of your posts.
Please don't feed him. Please!
Kind regards, and in the interests of the Northern Sounds forum.
