It seems complicated and pointless to keep an acceptable ads list, if I'm going to block some, why not block them all? While I only really care about blocking badly behaved ads, the easiest way to do so is to block all of them.
Also, the fact that they are taking money to get on the 'acceptable ads' list looks a little shady. It could be (let's be generous) misinterpreted as a third party just elbowing in to get a cut of the transaction, like some kind of protection racket. I'd worry this sort of thing might draw unwanted attention in some jurisdictions, even if it really isn't warranted.
Why bother going with the solution that is both technically and ethically more complicated? Just do the dumb thing and block everything.
