I disagree with the entire premise of this topic. Yes topics can go off the rails, but you are painting this as we just ganged up on Natsu/Suzy Q and derailed the topic because he posted.
Natsu/Suzy Q creates the situations in which responses are garnered towards him. The other topic is a perfect example. The first sentence of his response was more than adequate of a response. He chose to then take aim at PRO and Nelson, which was an invitation for others to toss right back at him. The problems he has are of his own making.
As well, players don't just take aim at every post he makes. Case and Point, Fantasy Draft Chit Chat III. Natsu/Suzy Q has posted within the chat without any comments being directed at him.
On a side note, the "Heads Up" topic wasn't exactly what I would call a clear and cut discussion on any particular topic. It should have been in the UoH based on the first post. Additionally if it was a game discussion on WDs, it should have been in the Game Discussion Section of Forums and not the Tavern.
