If multi-accounting using false identities is illegal in terms of the T&Cs that a player agrees to abide by, then surely the ethical question is answered?
I thought it referred to a situation where a player "gnomed" using another's identity with their full agreement and cooperation, rather than merely using false details. The "gnome" does all the playing, but for a fee or other consideration, the person who's identity is being used agrees to provide things like ID documents, phone verification, etc when withdrawals are made. The person being "gnomed" would also set up official accounts in their own name and hand them over the the actual player to operate them.
The incentive is to have multiple goes at "one per player" promotions, or in the case of player on player action (poker for example), to make it hard for others to know who they are playing, which is something Bodog poker feel is a good thing.
IDs are likely used from people who are themselves not interested in online gambling, but are prepared to allow themselves to be involved for some type of reward if another does all the "work". There must be a huge number of potential IDs that can be used this way.
Frauds also use other people's IDs for free by impersonating them and getting hold of supporting documents, some of which are genuine if government agencies have been duped into believing the "gnome" is actually the proper owner of the ID.
A scandal outside of online casinos (benefit fraud) has shown that some resort to tracking down those who died in childhood, and then trying to trick the system into thinking they are alive an well as adults, and then claiming all state aid possible in their names. This is considered particularly "nasty" as the bereaved parents can end up with a "bolt from the blue" decades after their child has died because the fraud has linked back to them. The approach works because those who die in childhood are never given things like a NI number, and thus it is easier to trick the system into granting one by saying that they were brought up abroad and have just returned. Checks simply show nothing untoward since the ID has never before been tracked through government databases such as tax, benefits, etc.
It is highly likely the SAME technique is being used at online casinos.
