- DDOS attacks, if those don't work aggressively go after Cloudflare or their DDOS shield
- Pressure their payment processors to deplatform them
- Get Visa and Mastercard to drop these sites
- Once they have no DDOS shield, pressure their hosting providers to drop them
- Set up landing pages to bump them out of search results
- Aggressively pressure Pinterest et al. to take down any posts with "Ripoff Report" or "Cheat Alert" in the name
A similar playbook to Gab/Parler, but efforts like this would really, tangibly help people and right a serious wrong that can affect anyone, regardless their beliefs or politics.
