Keeping them blocked is an incentive for them to fix the spf dns records.
Just like im not going to whitelist a mail server because some twit doesnt 
know how to configure DNS, or whitelist some server because they can't 
stop their spammers who keep getting them into RBL's.

The more that enforce it, the better chance there is of THEM getting off 
their lazy but and fixing THEIR problem.

If they have no clue, offer to fix it for them, at a nice cost of course
