Hi Bill,
We can't know for sure what you did that was classified as misbehaviour (unless we knew your IP; and **please don't post your IP address in a reply to this message, this is a public group!**) but this is what it looks like when you are blocked for misbehaviour.
The sort of thing that counts is malformed requests, or just too many requests. Please wait a little while, and try again, keeping this in mind. If you're still having trouble after waiting an hour, then please contact us privately at info [zat] commoncrawl [zot] org and we can investigate further.
All best,
TV
