Bohemia told Bamf to get rid of it around the end of October 2018.
Anything that provides the slightest gameplay advantage is against Arma 3's monetization rules. Spawning with a debit card is a gameplay advantage.
"Monetization happens when players, unlike with donations, receive some kind of reward or perk for their money. This requires our approval. Some examples of allowed rewards are perks which do not affect gameplay, e.g. custom textures, skins, forum badges, reserved slots, product placement, in-game advertising and sponsorship. You can also sell in-game items which do not affect gameplay in any way (e.g. special hats, designed shirts with logos, etc.) – generally everything cosmetic is allowed." https://www.bohemia.net/monetization
