These are pirated profiles. No way he has bought profiles for $41,000!
I have bought more profiles than this guy is offering: No way I have payed $41.000 or something! If you buy using deals, black fridays, bundles and have good contact with sellers you are able to legally build up a huge collection without getting destitute - and you are supporting the vendors (you like) and Kemper community in some way too.
If someone really sells his Kemper and gets an extra, cause of the profiles he offers as an bonus (one time!!!), I think that is not the problem. But this here is another case: Selling MULTIPLE times just is not o.k. - everyone knows this!
