Hello, yesterday a troll posted more than 2000 requests in a row and then deleted his account. Which means that even a moderator can only delete them one by one. As I have already asked you, you must limit the number of posts per user (EX: 10/Hour or 10/12Hour) to limit the damage.
Good day
Limit the number of posts
Re: Limit the number of posts
Rate limits are a common approach - Many online platforms use rate limits to prevent abuse and ensure fair use of the system. Limiting the number ofuno online posts per user per hour or day is a standard way to achieve this.
