Too racy. And thank you very much for asking, as I was one of the original complainers. It is hard to believe but there is a big difference between swim suit pictures and underwear pictures (and most people can tell the difference.)
Even if there are billboard size ads out there, and catalogs and print ads in every newspaper and magazine, their existence doesn't say "she's looking at underwear ads right now". Yes, as MaryK says, she looks like she is taking off her clothes. I mean, who stands around, or even models, with their hands on the inside of their garments? In the position that you would use to either put them on or take them off?
Not that I feel I need to defend myself, but seeing this pop up on my screen if my boss (a man younger than I am) would happen to walk by (and we have a lax internet usage policy in general) would make me very uncomfortable. And so I would not look at YLF during work hours if this type ad came up again.
Again, thanks for asking.
