its worth suing someone because you believe they hacked your server to replace a 16X16 icon with that of another site... which of course, would cause serious damages to your own shitty / failing link lists from 1998.
i'm sure that if i was going to target a shitty, useless site, this would be my first avenue of attack as well.... i'd be up day and night thinking "how can i change favicons on a large scale - i'll rule the world".... then i'd target retarded webmasters who have a short fuse and low IQ so they'll run to the boards instantly and tell the world i'm quietly taking over.
