Yeah it might draw attention to the cause.
As a player on the other game, getting the message of "Sorry we are bogged down because people from another game are flooding our system in protest." and then going "hmm I should join those guys." It was more like "God dang it. Who are these d-wads?" and made me want to stay away because it seemed as if all they cared about was their cause but not being considerate to other players in other games.
But on the other end, it will probably will get attention but remember when doing things like this while trying to come up with a game under the Titan banner, we do not want to antagonize future players. When the game hits, we want them to think "hey, there goes those guys who game got pulledo ut from under them. They been doing great things for the community." and not "Hey, those are those pogues that got upset and tried to disrupt every game they can because their game got shutdown. I had to wait two hours beyond normal because they clogged the lines. Hell no, I dont want anything to do with them."
I'm not saying dont do it, but just be mindful. Even though I wish things like this could be kept a bit more secrect because now if someone from there happens to read this, they will be ready to deal with the flood of tickets from COX complaints and might not garner the attention at all and or the point being missed and merely labeled "as those angry people that are upset over the closing of COX, ignore them. Tomorrow, we wont have to deal with them.
