SEO spammers or some other kind?

Today’s Federati mail:
1: someone that wants a price that they can pay to put content on Nu.
2: someone asking directly whether they can post an article

At least, that’s what their titles said. Not having time for spammers, I marked them spam and then deleted them.

(I must have configured something wrong. I usually do the “local only” mail config, so I don’t have to worry about spam or about the dance of approval by Google/Microsoft/Yahoo.)
