Note to errant botmeisters: bots that observe the robots.txt standard should not crawl sites where the file contains a 'deny all' setting, unless there is a prior 'allow' setting for that bot. A 'deny all' setting is consecutive lines 'User-agent: *' & 'Disallow: /'; an 'allow' setting is consecutive lines 'User-agent: Thatbot' & 'Disallow:'.
Webmasters are not required to individually block the myriad unwanted bots. RTFM!
Except on this site, badly behaved bots will be 403'd and the client IP addresses indefinitely banned from the server by firewall rules.
