You can have more anonymity by mining an account. I'm sure there will be a way to purchase an account using crypto this is well received in the community. Once get this far then you could use a private VPN service to post to steemit.com.. Many VPN providers accept crypto as payment. Posts on steemit are mirrored by at least 21 elected witnesses (see the witnesses in the sidebar), so, Steemit.com is just a web page on top of steemd (what the witnesses run). Steemit.com respects privacy but they could be court orderd, or (in the USA) simply harrased by government agencies into turning over records.. I'm not aware of any data policy that details what steemit is saving and will not save.

I hope you have something good to share to help people gain their freedom!
