======Synopsis:======
[[set]] no_ctcp_flood [on|off|toggle]

======Description:======
When turned on, the client will only return at most one [[CTCP]] reply every
2 (two) seconds to any particular nickname.  Additional [[CTCP]] requests
within that time frame are simply ignored.

======Other Notes:======
The client checks this variable on a per-nickname basis.  This makes it
ineffective when being flooded by multiple clients in concert.
