Is the community different?

I came over from Tabor, just got the game yesterday and didn't play any raids yet. I've seen people talking about meeting Randoms mid raid and hanging out with them, splitting loot, etc.

I was mostly just wondering, is there anything the community dies to let you know they are friendly if they aren't using their mics? Also curious of how often you find friendly people. I don't want to be stuck in the mindset Tabor gave me with "I'm friendly I have nothing" and be met with a shotgun to my head.
