Because in order to let you talk to people, you have to be able to reach their computer. It's no different than how 8moe is only anonymous between posters. The server has to be able to see you or else you wouldn't be able to post on the site. And with Zeronet being decentralized, there is no master server to keep track of anything, so each site had to independently issue an identity key so that it could talk to your computer. Those keys are trivially easy to delete and request, which makes spam impossible to limit. Furthermore, being decentralized means there are no mods and no mod tools for the removal of spam - each user has to delete it from his or her copy themselves, which is a lot of work. tl;dr imagine 8moe being spammed across every board at a rate of two to four thousands posts per hour, 24 hours a day, there are no mods, and you can only hide one post at a time. Zerochan was forced to use a third party ID service that limited users to 1 ID per IP address to stop the spam, but the damage was already done.
