I am on record in pretty much every thread like this as being in full support of Basicwiz and all he does and tries to do, and I am so again, but . . .

There is a difference between not feedng a troll and slaying it.  Pushing one away with warnings, cleaning up after it with post deletions, and pretending it does not exist with any form of ignore feature are all useless.

Ban the beasts.  Put a guard at the gate and just kill the things when they appear.

I forget where I read this - maybe I made it up when I was tired and forgot:  "Zombies are not pets - even the cutest ones will, at some point, will require a shotgun blast to the head."

Pulling the trigger on one will probably not deter then next, but it should be easier than arm wresting a programmer for ignore codes and spending hours removing comments.
