This feature already exists. All you have to do is travel back in time and stop them from signing up. And, when you got, I have a list if you have extra time in your time travel...
@avocado Doesn't make the request any less valid. I love mlkshk, but am completely turned off by some users (animal/people abuse, porn, pic flooding, etc.) This means I can't always look at Popular, Incoming or certain shakes. The lack of this feature was enough to make me not renew my subscription. When it gets added, I will renew.
@subbes ...oh it's a thing alright. Like when most people would post one cool image and put a link to the rest, the pic dumper posts every single image all at one time. Like the light bulb avatar.
