To avoid impersonation if the account goes dormant (gets deleted), I’ve been scheduling single posts to post on my old twitter once a week.
They invite people to join me on other platforms. I’ve basically deleted all other posts I made on twitter since 2008.
Today, I changed messages going forward to no longer direct people to meta platforms, and instead just to these:

I expect I'm less likely to be a target of impersonation but I also did not delete there for the same reasons.
I'm glad to see you modelling data ethics this way.
