Yep if you don’t fall inline exactly with whatever’s subs hivemind feels is the correct side to be on it’s a ban. Happened to me on /r/energy. Just made a very simple and non provocative comment about how I thought nuclear power should be considered more, instant ban. Wound up getting kicked off reddit completely because of that, it pissed me off so much I switched to a multi account and commented again. Reddit was cool but it’s time is up. Couldn’t be happier to give it up, I have not been back on it in a month now and I miss nothing.
