They can’t fingerprint your computer, that’s a lie that Moderators tell to non-techsavy users to discourage ban evasion, just use the browsing history data you and the browser voluntarily give them, use Reddit through Tor and it won’t be effective, you can harass their admins constantly and they can’t do a thing about it, just keep banning the accounts (unless they want to Ban Tor which I don’t forsee happening at least for a while).
Just don’t try pushing your luck because if you say anything too evil (i.e. threats of mass violence, mass destruction, violence or harm against the government, etc.) Dpeartment of Investigation, FBI, or Secret Service could still come after you with Tor.
