A few weeks ago I noticed UA [Amanda_Spider/billy@al-info.com] from [ftwal1ubr5-4-hfc-0251-40e8e953.rdc1.fl.coxatwork.com] going crazy on my site, so I denied that IP in my .htaccess file. Just yesterday it tried again: 163 files in 5 minutes.
It's apparently a legit Alabama search enginge, but has a very badly behaved bot.
I didn't bother sending a note to billy.
