For the curious, I just got this reply from HN staff:

"That account triggered a spam filter when it posted from a banned site. I've unbanned that site, unbanned your account, and restored all your comments, so the problem is fixed now.

The site was banned because the first few submissions from it looked a lot like spam. Later submissions were legit, though, so this was a mistake at our end. I'm sorry about that.

Thanks for letting us know about the problem, and please write if there's anything else we can help with."
