I prefer to have comments open in case anyone wants to do so, but it looks like the only ones I get now (except for one a long while back) are from some Chinese spam engine. :(
I am going to be turning them off for at least the short term.
After investigation, I have some options to limit comments to registered users. Sorry if you want to make an anonymous comment, but I am going to try this to limit the spam links.
I would just delete this post, but I can't find an option to do so. :(
