In course of a trial against three neonazi leaders in Vienna the VPN provider “Perfect Privacy” was unmasked as basically run by Austrian and German neonazis. More details on this can be found in the following Indymedia article: http://de.indymedia.org/2012/05/330387.shtml
If you need a VPN provider but do not want to suppot nazis we suggest using other services like those of the radical tech collectives riseup.net and austici. For more infos also look up the Indymedia article above.
