I'm from Europe so my experiences are mostly from here:
My experience is that if you check in immidiately when you can and being at the airport early enough will be enough to get on. It's usually the late bees that get notified of overbooking issue.
Just check in asap when it becomes available and be at the airport early enough to be at the top of the line during boarding. I always check in 24/48 hours before the flight and have only once been notified of overbooking and possibility of not getting onboard. I immidiately went through security and was waiting for boarding close to the gate - got in.
Edit: also have only once selected seats in advance, didn't do so on Ryanair flight.
It's also about the barrier of entry. Discord has a barrier, but it is not high. The fact that this platform is their commercial product ensures that issues are minimal (well...). For non tech-savvy people and those who don't have time / don't want to put in time to troubleshoot and figure things out this is the reason they go for these commercial solutions.
Just my observations from trying to switch friends and family over to free open source alternatives. It was a huge hassle to even get people to try out and move to signal, but signal has lowered the barrier quite a bit and now it's stable (was not always as fast and stable as now).
There are programs for that! Even an app AFAIK, but sadly I don't remember the good ones right now. Maybe someone could pitch in and suggest?
Seems like it worked for me. Last I checked my deleted account's comments are still up and display replaced text.
I overwrote my comments with a message that clearly states why I overwrote my comments and deleted my account.
