Although a lot of these cards are scams not all of them are. Anonymous ATM cards are still the primary way that the vendors I know cash out, everything from pecunix to bitcoin, and I know that the cards work for some of them anyway and have for a long time. A lot of them are also scams though. Also I would avoid buying one on SR and instead look on places that are not directly tied to illegal activity. Also some of them require them to send in photocopies of ID and utility bill, but this is easily forged.
