From Mar 1 - Mar 6, my site (a site for lodge members, of which there are about 100) got 1500 comments. Before these 6 days, we had 13 total comments.
I went through, deleted all of them, made all comments held for moderation, turned on SI-Captcha plugin, and also selected the option that you must be registered and logged in to comment.
As of this morning (3 days later) I had 1600 new comments.
I double checked my settings, there is literally nothing else I can do. I don't know how or why I am getting these comments. There are only 3 accounts on my site, and I know who they belong to. When I log out, and go to an article, it states that I must be registered and logged in to comment.
Where are these coming from? How do I stop them?
