Yes. We've recently deployed a new spam blocking system that is partly fed by the signal that it receives from the community and moderators during the normal course of moderation, which includes getting rid of spam (and the accounts that post it).

If you see obvious and blatant spam like that, flag it as such. Moderators should also destroy these obvious throw-away accounts by selecting:

Mod -> Destroy -> "created exclusively to post spam or nonsense"

Note - this guidance is intended for the most obvious cases, which fortunately is the majority of the spam that we see. If an account has even a modicum of otherwise positive participation, more investigation is needed.

The post that I linked to has a link to a spreadsheet, where you'll find some of the junk that the system has been keeping out of Math Overflow over the last seven days or so. Accurately identifying this stuff and dealing with it quickly helps not just MathOverflow, but all sites in our network; just as MO now benefits from the work that other communities put into handling it.
