- Avoided players should not chat in your games
This I absolutely disagree with. Game chats should be open to everyone. I can understand why you might not want to be insulted or made fun of, but we already have rules against that and you can get chat banned if you chat inappropriately. I also enjoy talking with many players in game chats that I am not playing. It's fun to interact. Chats should be open to everyone, and whoever breaks the rules gets chat banned.
- Avoided players should not send you private messages
I disagree with this as well. However, maybe have a completely separate avoid list for private messages. Just because I might not like how a player plays does not mean I do not want to interact with them at all. I just prefer not to play with them specifically for various reasons. I think we need to remember that there could be many reasons why we avoid players. For me its usually either, I don't like their playstyle and it makes me vulnerable to losing points, or because their rank is extremely low that if I lose to them, I can lose so many points and if I win, I get barely anything. I usually use this reason to avoid for 1v1 games. I don't want to play 1v1 games with people that I will only get like 1-4 points for a win and lose 30+ if I lose.
The only other reason I might avoid a player is if they have a terrible attendance reputation.
However, all of those reasons for me it is just about playing the game. I do not dislike them or want to avoid communication. I just don't want to play with them.
All that to say, I support a completely different avoid list for private messages if you're getting harassed, etc.
