If you use an anonymous proxy-to-another anonymous-proxy-to-an anonymous email sender, you can pretty well effectively hide the fact it came from you. Of course you shouldn't do anything illegal with this, because it's still traceable by law enforcement, but it is a way to encapsulate from the eyes of a techie.
You could like, send a link to free-minds and make it look like it came from someone else.
Why not stir the pot a little, and get someone to think again?
