Unfortunately, DMCA abuse rarely has consequences for those behind it.
Oh look! The actual problem is buried at the end of the article.
It's my understanding that filing a DMCA request requires that you certify that you have reviewed the content, and confirm that you believe the content to be infringing.
Here's an excerpt from a sample takedown notice, provided by Georgetown University:
I am providing this notice in good faith and with the reasonable belief that my rights as the exclusive rights holder are being infringed.
Under penalty of perjury, I certify that the information contained in this notification is both true and accurate
I know that "reasonable belief" gives a lot of wiggle room from a legal standpoint, but c'mon. If no one pushes back on that, of course it will be abused!
To save you some time, it's Google's Ad Center, which the article doesn't even link to, as far as I can tell.
I'm not creeped out by any of the info I found in mine, but I am annoyed. "Yes, Google, I searched for [random thing] twice because I needed to know a little more information. That time has passed because I bought it or the event has passed or whatever. Reminding me about it just makes it weird."
