Ban or disable chat for abusive anonymous chess players

Please introduce a way to report or ban IP or disable chat for abusive anonymous players. Currently there is no way to report anonymous players on report forum. Hope something is done about such trolls or it will ruin the reputation of lichess.org

I have a really good idea for a solution. Maybe they could put into the chat area a little box that you could check or uncheck to have the chat on or not, according to your own preferences. And then if you encounter someone you don't want to chat with, you could simply ignore them! Wouldn't that be convenient?

Oh. Wait.

We really believe one of the strengths of the site is the opportunity to play anonymously.
Saying anonymous and then tracking them down would mean that something is not adding up, it's pretty straight forward.
Our policy is that we can't - and we won't - moderate anonymous games.

I'm aware of check box in chat but I often use the app & there's no option to disable chat notification.

#1 don't play against Anonymous players, you can abort the game if you want ..

Just do not play Anonymous players problem solved

"I'm aware of check box in chat but I often use the app & there's no option to disable chat notification."

You don't have to click on the chat button to see what they said.

EDIT: Just saw this is a 5 month old thread. Why.
