Friends? Friendly Chit Chat?

I’m newer to this platform-- so I’ll probably be throwing out a handful of questions in the next month to get on the same page.

I really enjoy the connection I see in this forum. I’m wondering if friendship outside of this platform in frowned upon? Are we allowed to connect playfully though pm’s? I asked someone about complaining re: a contest (in a very playful way). It makes sense that that’s frowned upon.

*I asked because it would be a little cathartic-- like in a real office setting.

Would anyone here be open to a friendly pm chit chat? Is conversation amongst creatives restricted to certain types of discourse?

I appreciate being able to ask. Thanks guys!
