Ask HN: Twitter's list feature a ploy to increase usage by risking reputations?

What prevents someone from creating a throwaway account, then creating a "losers" list say, and then adding a bunch of people to it?

Some of these people may eventually notice that they are on this "losers" list and block the person in question. But by then the damage to their reputation may have been done.

A better implementation would give you the option of approving each request to put you on a list. Moreover, if the list is renamed, then you would need to give your approval again.

If you are cynical, you might think this list implementation is a ploy to get you to check your twitter account frequently.
