Binds with .!xxxxx in them.

IMHO *all* "caution @ " messages are just spam and completely useless.

-100% of the players will receive a spam message
-90% are nowhere close to it
-10% of them may actually know the location you're saying
-0% care about it

The caution sign is the only sign that is directly related to the actual scene. That and the hazard sign is all you need to secure it. Use it wisely and report those who ignore them.
