Concerning Forced Anonymousity

Forced random tripcodes based on an IP hash. If everyone had a random (cycling after 24 hours, perhaps) tripcode/name, then we would be forever rid of that annoying "same person" crap that anonymous is so good at misdetecting. There'd be no attention whoring since everyone is on a level playing field.

Read this interesting suggestion in /a/ and thought I'd bring it here for all of you to see.
So... what do you think?

This would be a good way to prevent massive spamming as well, as you could easily point out the spammer and report him.

Is there any downside to this?
