Most yes, but not all. I don't think an auto-lock is the way to go, as you will end up killing some threads that will still have interesting discussion going on. Hopefully the proportion of interesting threads will increase with some of these new measure being put in place, and so the number of "false positives" that an automatic system would lock would increase. Better instead to just have a couple of dedicated mods for these boards who can increase spam removal, which will stop many threads reaching this point in the first place, and manually check and lock the ones which still become spamfests.
