For example, a site may not rank well if your server stops serving pages to Googlebot
Given how many spam bots are hitting our sites on a daily basis, and given that we try to fight that battle via htaccess "deny from" IPs, I would hope that Google would let you/us know in a GWT message if we accidentally blocked them. I don't know one way or the other if they will do that, but it would be certainly be helpful, and would remove the issue from the radar screen.
