I can't deny that I haven't felt tilted before from other players being salty... but keep in mind, verbally fighting back doesn't really help anything. You see it wouldn't be that big of a deal if it was to your face (to which I agree, if someone is consistently verbally harassing you outside of the game, you have all the power to make it stop however you want). This is online...there are faces on the other side of the screen, which is why it frustrates you right? That someone, another person is insulting YOU for how you play? I can understand that.
But this is a different case when it comes to reaction...this is in a MATCH, a game that you're devoted to for however long it takes to finish up. During that time, tensions can get high; you can get on tilt, you can get raving mad. But you know what? You're STILL in the game. It's not like a realistic scenario where you can deal with the issue and walk off when you wish, you have to fully finish the game before you can leave (otherwise you'll face the wrath of leavebuster). You made a commitment to a game that you should fully go through. They can be the MOST nasty players with what they say, but the point that others in the comments are trying to make is that responding to them doesn't help anything. It doesn't help YOU especially, because you're putting more mind into the argument than you are the game itself.
It's frustrating to receive the reports, but try to pay heed to your own words too. If they're being nasty, the best case scenario is to simply mute them and move on. You can handle it however you wish...it's just the most effective way to get around salty people.
TL;DR: Bitching back doesn't help anything, so mute button would be better.
