Each new generation on the web needs to learn that there’s no such thing as a permanent web identity on a commercial web service.
The only long-term solution to maintain your identity is:
1. your own domain name
2. Your own website/blog
3. Several backups
Everything else is temporary. Your accounts on myspace, facebook, medium, twitter, google plus, youtube, tiktok, mastodon will one day disappear or become useless.
You don’t have a "community" on those websites. Only ephemeral discussions.
