dont ask me why everything is in japanese
Nothing to ask about, it's because you're a weeaboo. :^)
I don't make enemies, so I don't need to have a private account.
At least not unless it's on League, and people are downright adversarial on League.
Someone my Titanfall group and I beat hard in CSGO a long time ago went into our Steam group's chat and kept calling us hackers. It went completely unnoticed for a while because we never use it, but eventually I kicked him.
It's kind of silly that I can't lock the group's chat without making it totally private, but oh well.
