If I walk into the club shop and pay cash for a ticket they don't know who I am either.
They will know the name you bought it under, and chances are you know them. If you go to the trouble of getting fake names to buy tickets, chances are you're not just a regular fan who has had one too many beers and got carried away, but a regular trouble maker and will be known to police so will be identified from cctv.
(again, devil's advocating here)
