# Ctcp avatar protocol options

A funnier IRC

First of all you should read the the AVATAR protocol specification.
The problems that might arise with this protocol are related to flood and spam.
You might be flooded with AVATAR requests with different filenames, and thus automatically reply by requesting the missing files;
The AVATR protocol might be also used for SPAM from unknown people.
KVIrc attempts to protect you from these "attacks".
The flood problem is solved by the ctcp flood protection engine: if you set it up, the CTCP AVATAR requests will be filtered too.
The SPAM problem has no definitive solution (just as the "common" DCC SEND or PRIVMSG spam).
The inconvenience arises when you request the missing images from the ctcp sender.
The "hard" solution is to never request missing images from other people: this can be set by disabling the "Request missing avatars" option.
Hard solutions are never optimal, so KVIrc uses also different strategies.
First of all, AVATAR change requests are ignored at all for users that are not well known (i.e. are not on a channel with you nor have an open query); this saves you from the common spam on channel part.
