Toxic game/ poor action by EA

Tsp8​ There is an in-game setting under the first settings page called "communication filter". You can change this setting from "everyone" to "friends only" or to "no one", which will block incoming voice and text chat from non-friends, (or everyone), however do keep in mind that your voice and text chat will still go through, (and if you manually unmute anyone, you would have to manually remute them if you wish for them to be automatically muted again).

While this setting has been awesome for me, it may not be a solution for you if you like to still talk to randoms on your team.

People can say whatever they want without consequence. But if you turn on your voice-to-text and start screenshotting and reporting THAT... then you might get some people banned.

But, as pointed out already, the best solution is to keep your squadmates muted until the point in the match where they might actually have something useful to say. Final three, maybe?

What reconzero​ pointed out is a good thing, however you should be aware that it is a two way street, your voice will be transmitted as text to the others as well.

You can also mute the other players if you do not want to deal with their toxicity.

[W]hat the Internet and its cult of anonymity do is to provide a blanket sort of immunity for anybody who wants to say anything about anybody else, and it would be difficult in this sense to think of a more morally deformed exploitation of the concept of free speech.

"morally deformed exploitation of the concept of free speech"

Very well said.
