Searching through the archives, it looks like there's also a few cases of
shared snippets and copy/pasted scripts sent to this list that were
infected.
They could have propagated just by copy-pasting them back.

These "layer infections" are so hard to track down and completely get rid
of...
Makes me think that maybe there should be a more restrictive policy
enforced by Nuke itself, where a layer/channel won't be created unless it
meets a certain criteria?
