I don't have discord, I had it once, the experience was very bad and it's been three years almost four years since I closed the account. I think it's best to interact first through Hive, to get to know certain things about the person, before using another medium.
In my case, I am very selective, too selective, there are people that I have met here first, then a filter of an email and then if it passes the filter another type of more direct communication, but I have very very few people with whom I interact outside of hive at the moment.
It's best to keep one's circle smaller I think, especially these days. A few good friends is better than many average ones.
That's what I do and I will stay that way.
