Gnoming / Multi-Accounting

How it works

A player uses multiple accounts to manipulate head-to-head or small-field games, ensuring one account wins while others lose—effectively playing against themselves to harvest bonuses or launder funds. The fraudster creates multiple accounts using different identities (stolen, synthetic, or friends/family). In head-to-head contests, one account is set up to lose deliberately. In tournament poker, multiple entries collude to eliminate other players.

On the record

Gnoming is widespread in daily fantasy sports, sports betting, and online poker. Some operators report that 5-15% of head-to-head matches involve some form of multi-accounting.
