Many people have had issues with returnpath. They claim to address issues, but most of my interactions with them have been unsatisfactory.
I've pointed out a meta-issue, which is that SA's score adjustment algorithm is reasonable for tests where senders and the tests don't have a relationship, but IMHO SA should have standards for whitelists that accept money to be listed. In my book that's a clear conflict of interest and it needs a clearly documented mitigation plan. Elements of the plan should involve having really obvious complaint paths, actually following up on those complaints, and reporting to the community about complaint handling. If a pay-to-play whitelist doesn't want to do that, they should be dropped from the default ruleset.
