Today one bot, which identified itself as Sean's Agent/1.0 (compatible; SA 1.0; Windows NT 6.0; SLCC1; .NET CLR 2.0.50727; .NET CLR 3.0.04506; .NET CLR 1.1.4322; made 10459 requests to one of my sites within two hours from the same IP address (184.108.40.206). The user agent comes from a C# sample. This is a good example how good code can be used for bad purposes.
Looks like somebody stupid took this sample and tried to build some kind of bot with it. This bot tried to grab the site in a very aggressive way, requesting the same page many times. What did it earn in the end? A permanent ban for IP address and this user agent on all my servers.
