On Swedissh Wikipedia chat channel we discussed the blocking of anonymous users.
One of our users thought that we are to lenient towards "graffiti-users",
meaning that serious users have to spend much time reverting articles. We are
however reluctant to block IP numbers, at least for any length of time, since
this would also block contributing users, especially since the IP numbers
typically are those of schools, libraries, and other institutions. From  our
discussion grew the following suggestion:

What if we could have "soft" and "hard" IP blocking, whereas soft blocking
blocks only anonymous users with a specific IP number? Registered users using
the same IP would still be able to edit. It would also be possible to register
as user. In this way we who are admins could be slightly more "trigger happy"
with the block button. The hard blocking would then only be used if someone
tried to mass-produce registered accounts to reach around the soft blocking.
