Thats just a straw man. I have never opposed filtering. Like all your moderators I have been tireless in deleting "blantant spam" so it has never been a problem for ordinary users. Over the years I have pleaded and argued with you to get a mandate for deleting low quaility posts and you have always refused it and insisted on strict interpretation of the Rules and nothing else.
Now it seems you have seen the value of supressing low quality posts, so we agree at last. What's left is to define "low quality" - off-topic, technically lacking, repetitive, badly written ...?
But before going down that rabbit hole answer this: what percentage of posts (after modertors have applied he Posting Rules) are of "low quality"? 5%, 10%, 2%? I don't think it's a lot. Personally I think allowing mods a bit of discretion is enough to get rid of the remaining problem.
But my specific problem was with the implementtion of filtering you have imposed, in which people don't see posts until people have seen them and up-voted them. Surely it's obvious that it's a nonsense? Your fix is to reverse a lifetime of insisting on moderation by the rules and expect mods to select posts for general viewing by giving them their first upvote based on... what?
So please trash-can this particular filtering and think through the whole filtering process before implementing a replacement.
