I know the obvious things like federation and fediverse, but do we say upvote/downvote, updoot, karma? I hate to bring up the software that must not be named, but I don’t know what else to call things.
I’d like to add to their comment. A lot of people are coming from very argumentative or abrasive communities, and sometimes their initial messaging will show that. If someone comes off way too hot headed try not to assume that they’re going to end up being a troll. They might just be riled up. I’ve had pretty good success in asking clarifying questions to get people to explain their view rather than just come in swinging.
