Benefits accured via account aging
Use account aging to escalate privileges.
Accounts created within 48 hours should be limited to 5 photos total, 5 posts the first day, and 10 posts each day thereafter.
After a week: allow 5 photos per day, and keep 10 posts per day as a limit.
After a month: allow 10 photos per day and increase daily posting limit to 25.
After a year: clear all limits so users can post photos and content just as they do today.
This will reduce troll accounts, spam accounts… and… will also encourage members to keep their accounts instead of deleting then coming back to create a new account.
