Love the anon feature on here, however there is something that I must suggest.
Once I've posted, you will have no idea if it is the actual anon OP responding in the comments or if another user is impersonating the anon OP.
This could cause some headaches in the future when it comes to whistleblowers or recurring anon users returning to discussion vs being impersonated.
The anons require some ability to "prove" their identity if they do so choose.
My suggestion is the inclusion of an optional SHA-256 hash generator that displays the last 8 digits of the hash as a tag next to the anon account if desired.
This way, no matter where I am, where I connect from, which device I am using, if I click the options menu and I can input the passphrase and post with my anon hash, then I will be able to prove to you I am anon [4c2e90b3].
Additionally: Click to expand the whole hash and view past threads/comments by this particular anon.
