The number of providers that either under their own nom de TER or an additional alias trash others for any reason (very real or imaged) on a semi public board.

This always causes me moments of thought about whether that personality type would respect the bounds I would like to see maintained in this hobby.

I like the enjoyment of the interaction behind closed doors and look to it as a respite from the dog eat dog everyday world.  To me doggie is a position not an attitude.
