What kind of social chats can get you banned?

Hi!

I've recently been concerned with following KA's Community Guidelines and avoiding being banned. I've been wondering...what type of social chatting can get me banned? I'm very chatty in programming teams and other's programs, and want to avoid turning KA into a social media app for myself. 

Also, what random topics are KA lenient with so long as they aren't disruptive? Can sharing the continent I live in & my timezone be considered social chatting? Maybe sharing a joke/goofing around but keeping it relevent to the program content or something related? What shows I like/have watched? Or even where I'd like to go for holiday?

I just want to be cautious.

Thx in advance!
