Sometimes, I get flagged with a communication warning like this. It doesn't happen often, 2-3 times over 1,500+ games.

Does it mean that I'm in a low-priority pool now?

Occasionally this communication warning pops up

I don't think I have ever insulted anyone in Dota 2. To double check, I checked the all-time and one-month word cloud (on OpenDota) of the most frequent words I used. Here is the result of my word cloud.

Perhaps the most noticeable phrases I use are "nice hero", "so lucky" and "all luck". Since Dota 2 heroes aren't very balanced, sometimes I do get frustrated against Tinker/AW abusers and said "nice hero". Especially when they narrowingly escapes death or turned the fight simply because of their hero overpowered mechanics, then i'll say "so lucky". The "all luck" phrase I usually used to describe myself when we won a game by a hair's breadth.

I usually only all chat with in-game chat phrases, which are not included here, or occasionally comment on a funny situation. All in all, I don't all chat much since there's not much need to do so.

However, I do team chat quite a lot. Primarily for strategic communication when it's too complicated to use voice. Currently I can't analyze this, but I don't remember ever calling anyone dog or other animal or threatening their parents with actions that apparently no keyboard warrior would have dared to actually do.

I noticed that sometimes the non-English speakers (i.e. the Russian-speakers) would react to my chat in a negative way. I assume it's mainly language barrier, like if we listen to conversations in russian we would probably feel like they are insulting each other. Would it perhaps be a possible reason for them to start hating and reporting me for communication abuse?

Or all they need is some hate for the player and just report them regardless?
