Looks like the ads I'm seeing were part of a pending investigation.
So May 5th onwards is open season.
If for example, I wanted to bid on blacknight, you can raise a complaint as normal but the ad will only be removed if the trademark term is in the ad copy. Note: it can still be used as an ad trigger (where previously it couldn't)
Complaint Procedure document has been updated -
