@timbray I just today saw a link to how to save archived tweets to the Internet Archive which people may want to consider?
PS. For me, I opted to delete EVERYTHING, including my followers, likes, you name it. I'm a crazy person as I had to do some of it manually. :) Yes, I know some is on backup servers somewhere. My hope is by deleting all content then deactivating, in the tech snafus that I expect to come, it all gets mangled. :)
