Why did I got muted like this?

All I did is I created a new character 1-2 days ago, and how did I got this? I checked on email and there nothing about this, also no notification about this too, I was trying to comment and it says you are muted, but I didn't do anything wrong, how could this happen?

Also this, the true reason...

Note: because of this, I have redacted some of the parts on my profile, but yeah, if I'm on other sites, use the same username here, but I can't put the link or else I will get muted again...

I figured out later on my spam email, they just muted me because of this reason, I'm no longer comments about other sites anymore, or else I might get banned
