i used to use referrer-bouncer plugin, but then i needed separate plugins
for comment spam. now bad-behaviour catches all these before a page is

if it seems i'm pushing bad-behaviour so much, it's because i'm sick of

if more people used this or a similar technique that blocks page access from
spambots, it'd make a big difference (for legit users and spammers -
depending on perspective) imho.
