I would love to see this implemented into the game as soon as possible, this is the best idea I've seen since cartel crystals were added to the game. I get extremely tired of the old report / ignore routine, it's at the point where I feel more needs to be done about the spammers instead of banning a few of them every day, since that obviously doesn't work.
While ignoring 5 - 10 spammers a day isn't THAT much of a hassle, that completely changes when I play on more than one character and have to ignore the same spammers over and over again, multiplying the amount of times I have to be annoyed by them exponentially. Seeing my chat flooded with Yells and basic General Chat spam is not the first thing I want to see when I log on, or ever.
I would really love to see a feature in this game that handles this without expecting the players to take care of it, as we are not the devs, moderators, customer service, ect ect ect. I have played MUCH simpler games that used C+ coding and still have an anti-spam feature in their coding, which didn't require me to constantly report "players".
