Edit up front to say, it's unfortunate that you read that one line and got extremely nervous rather than take anything else I had put into consideration.

I personally don't care where you post if you're being polite on the sub I moderate. I try to think of it like being the chairperson of a meeting, or the bartender at a local bar: Let people debate and disagree and even say stupid stuff, but if they say something obviously offensive or start name-calling, you get modded.

And if I then look at your comment history and see a stream of vitriolic behavior, that shows me it wasn't "just one time" you got out of hand, but a pattern of undesirable behavior.

I do know other subs, mostly political, that will instantly ban you if you have a different set of beliefs than they do. It's very frustrating. But that's not what I'm discussing here.

I was hopefully tactful enough in my wording to raise the concern with the sentiment but not make it an accusation. I'm obviously reading into a statement you made a bit offhand. Please understand that I'm not saying you engage in any malfeasance.

However, different subs run differently. I may well engage in a nuanced and sourced debate in one subreddit, and frankly tell someone off in another. Subreddits are communities and communities have different standards of behavior.

Likewise, community membership is a terrible proxy for actual opinions or beliefs. I belong to many communities I disagree with, but I find monitoring them to be useful and sometimes engage in debates. I've found my debates with anti-vaxxers to be very enlightening - I still think people should get vaxxed but I understand my opposition.

All of this to say that a top down examination of a profile without context is worse than useless - it is actively misleading.

Honest question: what's the alternative? Maybe sign-off from multiple mods on every action? That'd be a tough sell to require double, triple, or more time from mods. Some sort of random review of x% of mod actions maybe?

Have a N strikes policy, track in-sub user infractions.

Have a public moderation log.

Reddit is unfortunately woefully under-equipped for moderators so the above is a strictly out of band process for Reddit specifically.

There's definitely some "politics" where that's an extremely wise move. For example, people who regularly post in a subreddit dedicated to holocaust denial don't really deserve benefit of the doubt when they've already posted something bad enough to require moderator interaction in /r/lego.

I don't have to imagine. Many subs automatically ban you if you post in few specific subs.
