I have censored the referer and client real IP.
Someone is using newreply.php to spam a bunch of replys could you guys implement something to stop this like check if someone has requested this function too many times in the past however long (per ip) I know there is antispam with mybb but the person is not posting anything they are just making the process.

The first thing is to try to increment the memory limit of your site with this command. Obv 512M is an example.

ini_set('memory_limit','512M');

How many requests are the spammer sending for minute?
