These apps force you to give access to your contacts and send fake nudes to them if you don’t pay:

Anyone unable to pay these fees and charges faced even bigger problems. The apps required users to grant access to contacts when applying for a loan, and the companies would then threaten to message all of their contacts if they didn’t pay. One user said that the app company even threatened to create fake nudes of her, and to send these to her contacts. My friend’s sister used an app named white Kash to take a loan and now they’ve access to her contact list. They’re also threatening to send her nude pics (they morphed her face) to her contact list.

Unbelievably scummy, but debt collectors are the worst of the worst so this doesn’t surprise me.
