I decided to compile a list of sensible advice that forum users can take to improve their privacy. More suggestions are of course welcome!
I assume that various AI programs are already mass collecting information for anything related with specific IP addresses, names, usernames and style of writing.
Anyone that is using modern smartphone is in much worse situation for privacy and Tor on Android or iOS is not as good as on regular computers, plus there are many other things smartphones record about users (like we saw in recent CM incidents).
My main suggestion is to stop using smartphones and switch back to old mobile phones if you care about privacy, but if that is to drastic than use de-googled phone (GrapeheneOS is interesting).
Full IP addresses and geolocation data retained for months or even years. Your posts are [4-6] archived basically forever.
This is happening for almost all websites and forums, so it's even worse if someone used same real IP address on multiple websites.
Maybe you can add suggestion for people to use temp emails, or services that allow creation of alias and additional email addresses.
It would be perfect to self host your own email address, as we already saw how Proton mail and other ''private'' services can give all information to authorities.
Ironically: mix, tumble, CoinJoin or submarine-swap your campaign funds to a Lightning wallet. Anything that improves your on-chain privacy.
