FYI: People Using Blogger
Lately I've been getting an increased amount of spam comments from "anonymous" users, most of them in foreign languages. None are from legitimate users. I switched my settings to "Registered Users" and all of the anonymous comments have stopped! Hooray!
If you're having the same problem on "blogger," I'd suggest changing those settings. The good news..."Registered Users" includes anyone with any kind of verified ID such a Yahoo account or several other common sources, so you shouldn't lose any valid comments. At least I don't think so.
Hopefully these spammers won't find another way to get through. How annoying!
