On this meme in particular: I'm afraid of the implications of calling new users [whitey alts.] We lose all credibility. It's the 'Incredibles' catch 22: once EVERYONE is a not-see then NO ONE is.
On the bigger issue: membership forms. This will eliminate half of these people because no one on imgflip can follow instructions.
Make a simple meme form (or order me to, you're an elected official, I'm purely ceremonial.) People who can't be bothered to find it, fill out and submit it to the mods will be considered lurkers and their votes and opinions can be ignored as such. 99% of the bad actors on here can't stay in character for 3 comments in a row, let alone the 3 days necessarily for them to find fill out and submit a membership form.
And the one smart [bum] who fills the form out with 'yes' in every line, is gonna be the same guy who doesn't submit it to the right stream. Sorted.
