Short and simple: never, ever. Those choices simply don't line up with what I want out of a social media platform. I don't want them to commmercialize all my data.

However I can be found on mastodon and Lemmy. That said it's on a need to know basis. If you want to see what I do on there (or rather don't because i mostly read stuff) ask me for the details and you will get them in private.
