This so-called browser named Browsezilla used to get onto my site with the old UA:
"Mozilla/4.0 (compatible; MSIE 6.0; Windows NT 5.1; SV1; Browsezilla; .NET CLR 1.1.4322)"Then those obnoxious assholes stepped it up a level by inserting a goddamn HTML hyperlink into the UA which my bot blocker stops instantly thinking it's referrer spam.
Mozilla/4.0 (compatible; MSIE 6.0; Windows NT 5.0; <a href=http://browsezilla.org>Browsezilla </a>)Almost felt bad for the assholes using this shit browser being blocked and almost unblocked it for them, but decided to do a little research first and HOLY SHIT this thing appears to be evil.
Read this InternetNews alert and this Panda alert and this detailed post by Oliver on a NotePet and you'll probably agree it's a good idea all around just to block Browsezilla so their users will abandon this fucking malware before it's an epidemic
I'm thinking it's best left blocked and possibly redirected to the InternetNews article to scare the shit out of people using the damn thing.
