This morning when I edited this blog, I found that it was no longer blocked. I didn't expect to see any results until Monday.
I think the cause might have been that I used a back reference on a link to a newspaper. I forget what the actual coding is but I tacked on my blog address as the reference for the link. I thought I had done it at least twice, but I could only find one instance, which I removed.
The site might have been blocked only in that I had to take an extra step to do anything. I had to retype one of those squiggly sets of letters. On the first occurrence it took three tries to get it right; the letters were really mashed together.
