"If your updates consist mainly of links, and not personal updates;"
Which if they're doing an RSS>Twitter spool then this would be the case.
I'm guessing rather than just banning all their accounts, Twitter will probably reach out to them and do a biz dev deal or something... If there is a value to Quora in having these setup then there is a value they're prepared to pay Twitter for.
Twitter should nip it in the bud before we see stuff like Engadget's monster tag lists becoming twitter accounts spewing out 80 different tweets about the same story.
