I will never understand why there isn’t an international law enforcement agency with teeth, which can get rid of the bad actors.
You mean Team America, World Police?
Besides the fact that not much happens in the international public sector, law enforcement is more about deterrence than prevention. Criminals aren't deterred by law enforcement, so the bad actors never stop. Human nature's a bitch.
If they did focus on prevention instead, most of this could be... prevented. Create a treaty that mandates how critical infrastructure technology is created/sold. Consumer routers will stop being shit at security, and home devices are slowed-down in upstream spamming. That's a good chunk of the denial-of-service market gone, with no need to police the world.
...but the criminals are smart and intentionally avoid attacking the powerful, so nobody cares. Same reason organized crime still exists. It's poor people caught up in gang violence and crime, not rich people, so it persists.
