I may be wrong, but I believe South Korea has a centralized identity system that game companies use so this kind of thing can be tracked and enforced. I wouldn't be against a similar system being used in the USA.
Yes - all players in SK essentially require identity verification. Using other's is a crime. Cheating is generally not directly prosecuted, but in other part of fraud/gang activity such as illegal match fixing, betting, fraudulent gains (tournaments), etc.
At least in the US I cannot think of any cheats that don't violate the CFAA/DMCA.
I wouldn’t be either, except that IIRC in South Korea you use your social security number, and I don’t imagine Americans (or other Westerners) will be comfortable with handing that over to gaming companies.
