I suspect as the flow of 'AI'-powered 'brand management' spam grows, registrars will stop taking fraud complaints at all seriously, and the internet will get a little worse (because there certainly are legitimate cases).
About 5 or 6 days ago, I received these reports on our host (Linode) and from our registrar (iwantmyname). I expressed my disappointment in my responses to both of them but told them I had removed the page and disabled the account. Linode confirmed and closed the case. iwantmyname never responded. This evening, I got a downtime alert, and while debugging, I noticed that the domain status had been set to "serverHold" on iwantmyname's domain panel. We have no other abuse reports from iwantmyname other than this one. I'm assuming no one on their end "closed" the ticket, so it went into an automatic system to disable the domain after some number of days.

Yet, there is no liability shield for fraud allegations. The registrar is liable for all damages due to this downtime, which they wouldn't have been for a DMCA complaint.
