Known to be false information, yes. Unverified information is another
beast---a large proportion of our mathematical articles are currently
unreferenced, but almost certainly correct (and can be easily verified
by anyone knowledgeable in the field, or with access to an intro-level
textbook).
If it's an unverified half-sentence stub, perhaps we don't lose much by
simply deleting it. If it's a good article that just needs some
references added, though, we move backwards by deleting it and forcing
someone later to start from scratch.
