Used by the CTCP reply flood protection system. Setting NO_CTCP_FLOOD to OFF disables the system entirely.
Each time you are requested to send more than CTCP_REPLY_FLOOD_SIZE bytes in CTCP_REPLY_BACKLOG_SECONDS no ctcp replies will be done for CTCP_REPLY_IGNORE_SECONDS.
Known good values are 256 bytes/ 5s/ 10s.
This is a sliding window, i.e. you can't get caught sending too much because of a 5s boundary, and the checking is still active even if you don't reply anymore, which avoids replying again every 10s if you're under attack.
If your VERBOSE_CTCP is ON begins and ends of ignore periods will be shown.
