I'm not saying action doesn't need to be taken; cause if they are actually vandalizing pages then it does - but blocking IP addresses for an infinite amount of time can risk getting good editors caught in the same block.

IP addresses change over time - and they can be reassigned to almost anyone. That doesn't mean you don't have to block them infinitely, because if that is your option for it then you may as well do it - but this should always be noted when deciding to block IP addresses infinitely.
