"Request: POST" errors when mass-deleting comments (10+) and not reporting spam

I've found when I'm delting 10+ comments at a time and *not* reporting comments as spam to Mollom, I keep getting POST errors. We're running the site on Pantheon. The requests to Mollom cause my site to go offline for a bit.

Here's a an example of the error log:

Request: POST http://rest.mollom.com/v1/content/121010c4728c2a3ba1

SEVERITY debug

Is there anything I can do to ensure Mollom isn't reporting spam when I tell it not to? If I do report comments as spam, the most I can delete at a time is 5.
