I don't know what the exact definition of trolling is, so I guess I shouldn't have used that term. In any event, I have no problem hearing negativity about the team, the board would be dull without it. But there is a certain line that I believe is being crossed. Negativity is certainly allowed, but dishonorable intentions are not, according to forum rule #1. Can constant, over-the-top negativity be considered a form of dishonorable intent? I would sure think so.
The rules also state that "it is completely the discretion of SportsTwo staff to enforce any unwritten policies they deem fit" and that "we reserve the right to amend these rules at any time." So, even if you determine that the poster in question's intent is honorable, if the SportsTwo staff wanted to ban him for essentially any other reason, they certainly could. And if they can ban someone, why wouldn't the staff want to ban a poster that completely annoys the vast majority of the rest of their customers? It's simple business...if one customer is spending $50 a day at my restaurant, but is driving away $200 in business, I would get rid of him.
