For some of them I kind of lost access so I would need to write emails to instagram or whatever, for others I would need to remember and to access to each one of them and delete them.
The hardest would be gmail with people having my contacts from like 10 years ago…
Just don’t use them beyond the minimum. I need facebook to keep in contact with some people I know and for groups on there but I just check in once a week or so. linkedin I need for job hunting. once I retire I will keep it around to give people recommendations if I need to. honstely I abandone twitter but I only ever made one to stake my name. youtube is nice to keep track of creators I like but I mostly watch it not logged in. got rid of my reddit because the federation covers that.
