Recently, thanks to a remark by counterlight, I became aware that Blogger has changed how it handles comments. Now, if you go to the dashboard and choose "comments" you see three categories: "published", "awaiting moderation" and "spam. " I looked at the "spam" comments which go through a filter, and found quite a number in there were not spam, but were comments by blog regulars, including myself! All of which I promptly approved. There have been no further inappropriate designations.
So, blogmasters, drop into the comments tab occasionally and make sure that blogger isn't mis-labeling your commenters.
As for OUR comment policy at FoJ: we do moderate the comments to this blog. There is no posting on older posts without active approval by one of us. We give wide latitude to comments on current posts, but we will delete any that we consider inappropriate (and potentially anyone else's that responded). We follow Jake's rule: it's our house, and you are here as our guests. Our loyal readers can help by (1) not responding to obvious trolling, and (2) letting us know if you notice anything wrong.
