I would like to underline "what you are looking at", posting content can still be tracked and if they are able to link the account to the associated person, this will be more than suspicious. This link is not impossible to make for sites like Patreon, the account name could have been mentioned in bank account statements, tax declarations and similar documents.Just for the case that Patreon is banned in Russia, if any of Russian or Ukrainer wants to access Paetron or other internet resources that are banned by the gov, use V2Ray technology rather than VPN. And if you want to increase the security level, use TLS that is supported by V2Ray. In this case, it is nearly impossible for Putin to know what you are looking at, nor Biden.
The likelihood of that happening is not necessarily high, but "nearly impossible" is not impossible.
The safest route would be to not even login to the accounts, as some websites even publicly track the date of your last login.
