But it's the same with gmail and everything else like that, I don't see it being a problem of ActivityPub or Mastodon. There's keybase or having your own domain with some index.html where you can direct your followers to a new account is not that big of a deal nowdays. If having to host it somewhere is too much for you - use dot tel tld (https://en.wikipedia.org/wiki/.tel https://en.wikipedia.org/wiki/.tel). People that really want to read your ramblings will find you anyway.
