Blocking Players But Still See Their Chat

I've blocked a countless number of people in recent weeks (no, really, I lost count) due to their toxicity and such pre-game, in-game, and post-game. After each one, I proceed to report them for what they've done (which nets, on average, three or four punishments/bans a day) and I block them.

Now, it used to be that, when blocking said person, you could no longer see anything they typed, and you would have a much smaller chance (I'd hope) of being matched with or against that person.

However, I am noticing recently that, even after immediately blocking them, I am still seeing everything they type, so I have to sit through more of their bile and BS while I'm looking over stats/graphs and such. Makes me kind of wish I could report them multiple times, lol.

Can we get this fixed, please? Thanks.
