At some point clubs will need to get together and deal with this. I'm assuming that other clubs have this potential issue now. Given they all scan tickets it can't be rocket science to bring this all together in some way can it? Loyalty should really only be for attendance.
Yeah, I think it would require a few clubs (at least) to club their data together in order to persuade others to join in. I'm unclear where they'd stand legally in terms of privacy/data protection though...
