Multi accounting happens when the same user creates multiple accounts with different emails, devices, or identities to exploit offers and promotions.
It’s a fast-growing form of first-party misuse that traditional fraud systems can’t see.
Users create fake emails or use multiple accouting to claim the same discount over and over. Rediim connects those identities, so you stop abuse and protect your marketing spend.

Referral fraud looks like acquisition—but it’s not. Rediim identifies fake referrals and abusers across devices, so you only reward genuine users.
