A lot of spammers have been trying to put spam in blog comments here. Since I moderate all comments posted here with some strict guidelines (no spammers, no flamers, no completely off-topic posts, no support requests) none of these posts were made visible, but still it's annoying to have seven posts to moderate and have them all be spam.
A lot of spam blogs use CSS to hide the button to report the blog; to report a spam Blogger blog, go to
this link (or
this link) to report the offending URL.
