I have noticed that many users on here seem to be under the age of eighteen, with some openly stating their age and getting permabanned by the admins. So, I have come up with a solution to this problem of underage users circumventing e621's minimum age requirement:
Charge money to users who want to create an e621 account.
"WHAT!? but that would drive the vast majority of users off of the site!", many users suddenly object.
Not really. If the administration of e621 wants to make sure that the users on here are actually legal adults, then they should implement a price for creating an account. In addition to that, the email verification system (which would come before charging the money) should be able to request access to the email user's age shown on their account. If the age shown on the email account is under the age of eighteen, they will be redirected to a page that has a "ACCESS DENIED: You do not meet the minimum age requirement to join this site" notice.
"What would the price be to join the website?", you ask.
I'll leave that to the admins, but I would say somewhere between six to ten dollars would be a good price.
