I didn't remember the site, but the other day I saw one of this deceptive cookie banners that tries to trick you to accept all cookies and make you do many steps to reject.
I noticed that the banner was made by "One Trust", and if you go to One Trust site, the examples showed are not deceptive at all [1], all the examples have a clear "Reject all"/"Accept all" buttons.
One Trust marketing page is hiding that has deceptive designs built in.
I guess the OP can make GDPR complaints to One Trust and services like that, and fix in bulk the sites that are using those services (or make it lose clients and shut down).
