If they are costly, and if they use so many resources, then they're not
very good solutions.  It's not difficult at all to construct very cheap,
very efficient anti-spam solutions which exhibit good performance
characteristics (that is: low FP, low FN, no backscatter, no spamming,
no special MUA/MTA software needed, etc.)

The fact that some (many?) people choose not to avail themselves of these
methods is unfortunate, but doesn't invalidate the methods.
