Question #2: Experiment

[Once again, sorry, no politics today.]

Just for giggles, I tried an experiment.

Three days ago I clicked a wrong button on Blogger and disabled comments for two posts. I finally realized my error and it was reconciled. In the process, I tried this experiment:

In the area where I could limit comments, I changed the comments setting from "Registered Users" to "anyone" which would include every person or entity who might be anonymous.

In less than two days, my Blogger Spam locker built up to over 49 comments.

Luckily, Blogger recognized these entries as spam and shunted them aside.

One got through to my standard comments moderation area.

But, in essentially one day, I was (for me, at least!) bombarded with spam comments from who-knows-whom. It was as if I had ladled continual buckets of bloody chum into the waters off New Smyrna Beach, Florida (per International Shark Attack File, it is the shark attack capital of the world).

Question: how do Spammers know this and how do they manage to react so incredibly quickly?
