Most marketers don't care. It happens, but very very rarely - the cost 
benefits of pre-scrubbing a few million numbers this way tends to 
outweigh the occasional sale they'll get hitting one of these (remember, 
the call to conversion ratio is typically amazingly low to begin with). 
If things do move back to landline, it's usually stuff that started that 
way. Many people have wireless numbers not in their home ratecenter 
(because wireless carriers do things by MSA and never really had to 
care) and most landline carriers won't port it to a landline if it's out 
of ratecenter.
