pingdom sacking my site’s resources [closed]

It appears that somebody created a pingdom account to ping my site once a minute, and since my website isn’t hosted on a very strong server anyway, those requests get heavy and slow down the server, will blocking pingdom’s servers through .htaccess help? will it use less resources then when pingdom just downloads my entire homepage?
and if it will, is there a way to block them based on user agent? their IP always changes, but the user agent stay the same Pingdom.com_bot_version_1.4_(http://www.pingdom.com/)

Answer

I’d do it via iptables.

Pingdom have a specific set of IP addresses they use, and, unsurprisingly, make the list public.

You could retrieve the list, and script the process of creating iptables drop rules for them.
