I have put together a few charts, with block activity for the period of February 19 - March 7th. May do more with this data later, tonight.

My perception that vandalism drops off significantly on the weekends is true. I also recall a sharp increase in vandalism last September when school resumed in the U.S. and other places.
Vandalism is also highest during the day and evenings (in the U.S.), the U.S. is by far the biggest source of vandalism, and schools/universities comprise approximately 1/4 of all vandalism from IP addresses.
This is interesting data. I should add that I have observed that activity on this mailing list also drops dramatically on Saturdays.
I think this means I (and others) need to make blocks of school IPs be for longer duration... the same for other repeat vandals.
Not at all. That's a simplistic solution. Such blocks would have an effect of blocking all users from the school, including the good ones who do not condone vandalism. Developping some kind of working arrangement with the school involved would make more sense. Work with them to identify and deal with the offenders at a local level. Find out if they have local policies requiring students to log on that would lead to a possible identification of which users were on line at the time that the vandalism took place.
