The story posted twice and removed by mods, were because he broke the rules. First he posted on c/technology when it has nothing to do with tech. Then he posted on c/news with a headline complaining that it was removed, where it’s against the rules to change the headline. So this has nothing to do with being silenced, but everything to do with not respecting the subs he posted to.
The exact same article was posted again, but with correct headline, and has not been taken down.
