without going into specifics, I've just had half my ads disapproved for being in contravention of a trademark. These ads have been running for 5 years and the abbreviation is of the type USA, RSVP, HTML - there's no chance it has been trademarked and if someone tried, they'd be laughed out of court.
As you know, getting in touch with a real person at google is nigh on impossible. I finally got a mail which said "you may reply to this mail" but that was two days ago.
What else can I do? The disapproved ads were big hitters and I'm showing half the ads I used to, all, I imagine, because of some dumb glitch "in the machine".
