A user created an account and sent spam messages to more than 300 members in less than 10 minutes. This is clearly not a copy and paste. It is like something executed with a software after account creation. They rush number of messages per minute to even bypass incase there is a limit set on outgoing messages per minute.
Is there a way to set a limit on outgoing messages per user per hour or even down to limiting outgoing messages per minute even if they attempt to use a software to rush them?
Could a captcha even have worked in this instance that the user is using software to send?
Found some code on buddypress forum to restrict users from sending private messages to those who are not their friends. Thats the fix I use for now. You can close this tkt if there is no other suggestion.
Thanks.
