There's only 9 of them. So probably it's not a big problem. (Although there are certainly some that I have missed.)
OTOH the recent posts on meta now have a bit lower visibility - since the five posts which were recently bumped by a spam answer are shown before them on the active tab.
Well, it's ten now. But this time it was posted as a question rather than answer - so the frontpage won't be disturbed in any way after the spam post is removed.
