Wikipedia:Long-term abuse/Hanover Research

Basic information
The Hanover Research vandal is a person or group of people who uses IPs in the Greater Washington, D.C., area, some of which are registered to Hanover Research Council, a for-profit public relations agency in Arlington, Virginia. The vandal violates WP:NPOV and WP:NOR by posting slanted political analysis based on selected voting statistics. A common practice is for the vandal to insert a chart of presidential election voting results for various California cities, and to edit-war it back in when removed. Other states and political entities have also been targeted.

The vandal has been blocked and rangeblocked many times. Noticeboard discussions about this vandal have been archived here:

The vandal scoffs at blocking methods: "You will never win this. I have countless IP addresses up my sleeve..."
