someone to get a feel for how Wikipedia works. After that, the
software should tell them to register if they want to make further
contributions. This way the Wikipedia would remain inviting to newbies
but would add encouragement to enter the reputation-tracking system.
It wouldn't entirely stop anonymous vandalism, but it would make it
more difficult and would probably eliminate most of it.
I don't think anonymous vandalism is actually a big problem, in
practice. Most gets reverted quickly with relatively little effort, and
persistent vandals are IP-banned (and can be IP-banned by any sysop
without prior authorization). The really sticky issues seem to be
problem users with accounts, especially those who are not doing simple
vandalism, but are causing problems in other ways.
