I would love to see an outright ban on partisan politics in the main forum. (For the P&S forum, well, that's what it's for).
I don't think that's necessary. If it's off-topic, you can already report it and it gets removed. If it's on the wrong board, report it and it gets moved.
There is a function like that as I see it, the report to moderator key note but most times, for user that have clicked and didn’t get the reports handled as they would have hoped, a ban of such habit seems the likely means to an effect.
Well, I think the pathway to having reports handled is effective reporting by stating reasons clearly and on point. It wouldn’t be difficult for a moderator to evaluate and decide on what to do. Eventually, that’s all they’ve been doing with the reports.
For politics, I don’t see how it has helped so much and I don’t see a reason why it ought to be all that should be campaigned about on the forum. It can take a late seat somewhere at the back.
