Avoid using your real name as username because some members used to register with their own name and few of them managed to get them changed by requesting theymos but in future it should be avoided.

I used Tor for accessing bitcointalk but even though the forum UI is simple which still feels lags while clicking thread or posting so I am mostly using it on chromium but only in my personal devices and I never logged in from any other devices and also I am using always logged in feature so captcha doesn't bother me much.

Privacy is not my ultimate priority but who really needs should practice all the points mentioned by OP to achieve it.
