I think it should be possible to do this in your client.

Basically, when you scan, there's these lines like:
***** Range 4 *****

Then there's maybe stuff after that line, then finally a blank line.

You could set up your client to gag starting at the ***** Range X ***** lines you don't want to see, and stop at the blank line. (And, if you're as paranoid about gagging as I am, turn off this whole thing as soon as you get your next prompt. Actually, if you're as paranoid about gagging as I am, you won't even try to implement this, but that's just a detail.)
