I’m not exactly sure how to read this post except this part “to disassociate GH from my Tor Forum acct”. No idea about “Deep technical plans etc, etc…”
To disassociate GH from Tor is as simple as creating a separate password for this forum and using it. Yes, I know, the Tor browser will not fill it in for you so you will need to store it in the little grey cells or in your regular browser and manually fetch it each time.
There is still an entry in GH for Tor but they will have no idea if you log in directly using the new password.
