SecurityGuard is a good verifed bot for the security of all users. With the anti-link/anti-ghostping function, you can block the link on the server, but still set where you can advertise. With the ticket system, users can get a little support! In the moderation category, there are also many commands for security, such as sg! Lock with which you can block a chat and this for all users who have no special rights. There are regular updates with new functions and more!
