It has become quite silly. I had a comment rejected because I entered a date using slash marks, which the nanny bot interpreted as part of web address. I had to change the slashes to dashes. And I have never seen an explanation for why they do this, well, at least not one that makes any sense.
It was a sad day when Sunshine stopped making Hydrox. Whole Foods sells a Hydrox-like cookie that, based on memories from long ago, is an excellent copy.
When I started reading comments on GC, they were not posting actual links, just URLs in plain text. So that should not have been a concern.
