I've had automatic deletion of all my tweets older than a few months enabled for a few years now. I wish I could do the same for Facebook.

(I did go through the FB history one night manually and deleted some of the edgier shit I posted well over a decade ago - I'm not that person any more).

Fastmail masked emails for all mailing lists and random sites. It's easy to sort them when the address is used only by one location - and as easy to drop if they start spamming.

1Password generated passwords for everything has been the standard for a decade now.

I use my real name only on sites where linking the content I create being linked to my person isn't a bad thing. (Books I've read, a few social media sites where I curate what I post etc).

I'm lucky because young me picked a really popular book with a cool character to choose my nickname from, so that's another way of obfuscating which account is mine and which are someone completely different.
