A friend of mine works in the Anti-SPAM group here
at Microsoft. When he joined the group, he was required to sign a disclaimer to signify
that he was aware that in the process of doing his job, he might see pornographic
and other possibly objectionable materials.
It makes sense, of course - wouldn't want some naive
employee to get offended and sue the company for putting such "offensive" material
in their faces (but then again, who with an email account doesn't see porn spam all
the time anyway?). But the overall idea of a disclaimer that says "Yes, it's okay
if I see porn" just cracks me up.
