Most of the improperly edited proofs here come from new members. My suggestion is to make a simple proof test as part of a member's introduction. It could be something as simple as a mock screenshot (fake of course) that has all kinds of information exposed names, IP's etc.. The starting member could then take the screenshot and edit it properly been repost. Proving that said member understands how to properly edit their proofs and post it with a proper image share service. I'm willing to provide some mock proofs if the staff likes a suggestion. I do not suggest this to make it harder to become a member but I do think it would help new members know what's expected of them.
I realize there are plenty of tutorials on proof editing here and yes I agree new member should read them as I did. I just don't think some of the new members do this which leads to a lot of posts being pulled. I feel it's unnecessary work for the staff to have the pull so many proofs down. even if it only cut down 50% of these. It may be worth it.
Just thought I had. Tell me what you think.
