So we should probably talk about CloudFlare as an accessory. Are they protected under Section 230? This appears to be illegal behavior and it was brought to their attention and they failed to take action.
How many "stressers" do you think the feds don't have time or motivation to care about getting subpoenas for? Because I can guarantee you there are more than the "four dozen" taken down here, and the vast majority have their identities and infrastructure protected by Cloudflare -- who also profits from their existence.
Cloudflare gets the low-integrity prize.
