I am using the SE app. Clicking on the achievement button I see a line stating " SE xxxx -10 user removed ".
I did very little activity on that SE and received very few upvotes.
I was never unpolite nor involved in sensitive topics or debates, especially because the SE topic in itself is unlikely to led to misbehaviour.
Does it really means that I have been removed and especially it is normal to be removed without warning or a more explicative notification?
Can I contact the moderator(s) of a specific SE and, if yes, how?
