So, to reiterate what has been said within the post in question:
Rule number two states:
Whatever happens in the community, stays within the community. Do not go to the offender's LJ or art site account and harass them, or contact them any other way if the matter under discussion does not regard you personally.
This includes harassing them at their place of employment or other means of income. Making someone lose their main source of income in no way assists in the resolution of their commission issues. Losing one's job does not exactly encourage one to spend time working on things already paid for that won't bring in more money.
This behavior goes well beyond simply harassing someone on a forum, and we moderators are taking a no-tolerance stance. If provided with proof of a person's involvement in this type of behavior, we will permanently ban that person. No three strikes.
And by the way, I'm gonna need those TPS reports by this afternoon.
