IP Blocked due to excessive hits

[darinburris]

Task works great, love it. However, I noticed, today, that it appeared that the task was failing to reach the W3C service due to what looked like network issues...the console output kept telling me the network was unavailable, 1st try, 2nd try and so forth before skipping each file.

Come to find out, my IP address has being blocked by the service itself due to too many validation requests, or what the W3C considered "unreasonable"

Is there any way around this apart from simply letting the block expire each time it happens?
