One thing I note regarding such spam is that it is generally from newer users, of which there are evergrowing numbers. While burning your hand on the stove if informative, it is also instructive to note that such burning is not informative to folks that didn't see it, or do it themselves.

With a tsunami of new users, I fear the flaghammer may prove necessary to wield forever. However, insofar as it is informative to each spammer on each post, I will hope that it has a salutary effect that benefits the community.

I also hope that it doesn't discourage too many newbs that just don't know better, or whose English hasn't reached a point where they're capable of knowing better, as it seems to have @hestiafull.
