If you set a custom ctcp reply and save then spam the user with ctcp it will eventually leak the real reply.

Example of the problem (spamming /ctcp version):

12:00 AM <username> VERSION - Custom CTCP Reply -
12:00 AM <username> VERSION - Custom CTCP Reply -
12:00 AM <username> VERSION - Custom CTCP Reply -
12:00 AM <username> VERSION - Custom CTCP Reply -
12:00 AM <username> VERSION - Custom CTCP Reply -
12:00 AM <username> VERSION - Custom CTCP Reply -
12:00 AM <username> VERSION * Client CTCP Reply *
