I always thought that trademarks were allowed in the ad title in Yahoo but I just got hundreds of ads ‘Editorial Declined’ and I can only guess that it is due to the trademark. What I don’t understand is that my competitors have their ad with trademarks appearing!
So is it a problem with the trademarks or could it be something else (not the URL they are working)?
I think this usually depends on editorial. Sometimes things go through, other times they do not. Also I have had it where something has been approved for a while, I make one change in my account and then my ads are disapproved. You should try submitting them again and see if they get approved. If not, it may be worth it to write an email to support.
