I think the inflammatory thread title puts people in a hostile mood before they even enter. It sounds really elitist but then when you read the actual request it's quickly apparent that it's a reasonable suggestion which helps everyone find a suitable party for what they want to do more effectively.

I'm struggling to think of a way that having more filters would make Party Finder worse; heck, it might make people use it more so more people can find groups, and nothing is stopping newcomers from making their own rival party finder groups that don't require a clear. The only thing that makes these requests go unanswered is that the staff probably don't realise how rough people have it. I would genuinely be shocked to find someone lying their way into a PF group I made without meeting the requirements because the culture is so different across regions; it sucks that it's such a problem on other servers.
