Occasionally mobs of hateful psychos will target individuals with harassment. There is absolutely not enough protection from unwanted messages, unwanted phone calls, false reports to SWAT teams, identity theft, who knows what else.

In Europe, a lot of the protection is that they have to provide their own identity to access the system. So I can host something on my internet connection, which is tied to my ID, and people can DoS it, but those people also have to provide ID for their own internet connections and can be traced, unless they are outside Europe in which case I can solve it by blocking all other countries. If someone spam-calls me from Europe, their phone is registered to their ID and caller ID is strictly enforced, so I know who is spamming me. For this reason there are few spam calls. If someone sends me a letter - well, I don't think sender address is mandatory because it couldn't be enforced. If someone wants to look up my details on the business registry, they leave a record showing who is looking them up.
