16 Republican subreddits
Multiple GOP "news" sites
I can try to come up with a comprehensive list if it's really worth it?
The loophole used to "justify" my bans is almost always:
User who doesn't agree with conservative narrative posts facts viewed as damaging -> Conservatives report you as "spamming" -> powers that be ban you as a "spammer" due to moderation mechanisms based on N reports.
Sometimes it involves human intervention as well, sometimes not.
For instance:
https://old.reddit.com/r/The_Donald/comments/96h0dy/pc_case_...
> PC case maker CaseLabs says it has been 'forced into bankruptcy and liquidation' by US tariffs (Prices went up 80%!) -- Thanks Folks and I await your censorship ban.
I know they are going to do that after I posted that, even included it in the title, and was banned. :)
I was also banned for similar posts on a couple news sites.

Pretty much any major "Conservative" subreddit has banned my account (or another one of my Reddit accounts) at this point. Voat/Gab, I'm banned platform wide.
Re: "Conservatives have a far, far lower bar to censor people than Twitter, et al. (i.e. /r/The_Donald on Reddit)" This is a generalization with only one example for support.
