They send a DMCA notice to a Hollywood studio... then what? Will production committee pull the movie out of cinema? Will they recall blu-ray disks from shops to destroy them?
DMCA offers no way to negotiate compensation or receive payment — "artists, musicians, and photographers" still have to sue to get paid.
In my theoretical example, let's say Disney slapped this person with a DMCA for the Loki look. Instead of just sending the DMCA request, they would also need to put $10,000 in escrow, and then open a meeting with an arbitrator for review.
The arbitrator's job would not be to assess it's validity, but would be to only determine whether the DMCA was frivolous or not. If the arbitrator rules it's frivolous, the $10,000 gets sent to the person pretending to be Loki. If the arbitrator rules not frivolous, the $10,000 that Disney put in escrow gets returned and it plays out like a normal DMCA.
The whole point is just that Disney, or the person filing the request, would be putting $10,000 on the line with the risk the arbitrator could rule it frivolous. If Disney disagrees, they can open a full lawsuit against the person, but that's a big risk on both sides that could still have abuse.
I'm just spitting out ideas. Maybe something like this could get refinement.
A few years ago, when I was in college, a friend had his art stolen from his website and reused on social media by a mid-sized company. A DMCA takedown solved the issue, but being a poor college student there is no way he could have found $10k lying around to use for takedown, even temporarily.
"You could also make the amount required variable to company size. Small company under $1M in revenue? $500. $1-$100M? $5000. $100M+? $10000. IDK, just something."
