Reason Bans "Malicious Comments"?

I just posted a comment at Reason and was re-directed to a page, after hitting "submit," that reads as follows:

Hit and Run
Continuous news, views, and abuse by the Reason staff
Thank You for Commenting
Your comment has been received. To protect against malicious comments, I have enabled a feature that allows your comments to be held for approval the first time you post a comment. I'll approve your comment when convenient; there is no need to re-post your comment. Return to the comment page

The first time I posted a comment was a couple of years ago, so tis a bit late for that; plus, this particular comment was actually quite benevolent. (I quoted from and linked to another Reason post.) I hope this is just a Moveable Type hiccup (not unprecedented at their well-trafficked site) and not some new editorial policy.
