So, suppose you're playing on USW4 and someone keeps spamming, "Selling stranges! Check my bp! !bp Pootisboy69!"about eight times per round.
I think that should be a mute-worthy offense because seeing this so often is very irritating. It gets even distracting, and could be considered "team harming" to an extent.
The rule would be that players could maybe have 5 trade spams per round tops. With a warning at 4. I've been using this rule on USW4 for a while, and it seems to work very well.
