All my online friends I have through Discord. Can't really help much beyond that, it's just kind of developed from regular contact over extended periods of time in shared spaces. Definitely helps when the space is a bit smaller though. The downside to it is that it can feel kinda fragile (at least in my experience). Like there have been a few moments (although fewer than you might think when we're all leftists lol) where a couple of my friends have gotten into a bad argument and one of them just leaves the sever, which at least for me makes it kind of hard to maintain things with them just because I'm not great one on one with people online.
