If you have a forum program (like FDR where we are, for example) you can pretty much do what you want, edit posts, delete them and that's what's happening to Ashton Birdie on Twitter:
Twitter and Facebook have obviously proved themselves amoral. Wordpress, who knows, it's still a program and will respond to its owner. Of course "spooks" are watching, or recording, it's what they do. From personal experience, if they want us they've got us. The Internet has convenient ways of listing us, which is wandering off your question, and it seems you're suffering the effect of people fiddling with your posts. But hey, suppression and their bs editing with never work, a lesson the commies eventually learned after their world got broken.
