I would... especially since the blockchain would show who is creating friend accounts to keep abusers out of the way. I man, I don't have 9999 friends, and if my account created that many.. well.. then you know something fishy is going on..
Personally, I'd like to see new accounts have to serve some sort of probationary period. If you don't write "ever"... or get upvoted "ever"... then perhaps after 30 days the account gets released again.
I don't know... as long as we can stop name hoarders from buying up every cool name in existence... I'm all for it.
