Here's one I haven't seen before....
Due to excessive bad posting from this IP or Subnet, comment posting has temporarily been disabled. If it's you, consider this a chance to sit in the timeout corner . If it's someone else, this is a chance to hunt them down. If you think this is unfair, please email firstname.lastname@example.org with your MD5'd IPID and SubnetID, which are "XXXXXXX" and "XXXXXXXX" and (optionally, but preferably) your IP number "a.b.c.d" and your username "southpolesammy".
This after my last 10 posts had a combined score of 28 points, including 3 Insightfuls and one each of Interesting, Informative, and Funny. So evidently, I must have pissed off some Slashdot editor with one of my posts.
Whatever guys -- it is your site, but this is bigger than the sum of its parts now, and you aren't the only fish in the sea.
