I don't know what ads get shown on LQ since I don't have them activated. You can always take that up with [edit: email address removed, please use the contact form]. And you don't have to use LQ at the office, that's your choice. Just as it is your choice not to pay as a contributing member, but you know that if you don't the possibility to deactivate ads is not a choice you have.
I'm not even going into a discussion about cultural differences here. But I don't consider ads about women's lingerie (like the screenshot you posted) offending, but that's just me.
