I've blocked 83.92.128.0/24 for 24 hours, as all four of the vandalbot IP addresses I saw go by are from that range. The range belongs to TeleDanmark (tele.dk), and claims to be part of their ADSL IP space. The full TeleDanmark space appears to be 83.88.0.0/13, but since the vandalbot appears to be working from the smaller space, I've only blocked that.
