Arbonne (https://www.arbonne.com) is one example and they proudly claim to be a B-Corp on their website right under the offer to join the pyramid scheme as an "independent consultant".

> then one would just tell B Corp to remove them the list no

This is not something that flew under the radar and can trivially be removed - the aforementioned company's business model is well known for example and despite that they became and are still a B-Corp.

My point is that B-Corp is happy to accept companies whose business model preys on and profits off vulnerable, financially-illiterate people, directly contradicting their claim of certifying companies which have a "positive impact on society, workers, the community and the environment" (from Wikipedia, emphasis mine).
