I thought that I had at last got rid of the spammers by making everyone become a member before they could post a comment.

No such luck as today there were three spam messages which somehow got through. I have gone through my list of members to see if anyone posted but nothing found in that section so it remains

How do they do that?

Well, I found out. They did it by posting comments to the photo gallery pictures which allows viewers to post comments. At least they did, I have closed that loophole now. As this spamming must be done by computers they are obviously very clever at finding any way they can to get into a website.

I hope that ends that problem
