So I was once a long time 49er's season ticket holder. One year, before the tickets were actually in my name, the person that received them lived in an apartment building in Oakland. When the tickets arrived they didn't fit in his mailbox and were left on a counter in front of the mailboxes for anyone to take. And sure enough they were stolen. Luckily we got replacement tickets just before the pre-season started. We show up to the first pre-season game and there are 4 people in my seats, whom I believe were the culprits. I let them know I'd be there for every game and the ushers made them leave. Every game thereafter a different group would show up claiming I was in their seats. I would just tell them to see the usher, the usher would come to me confirm my tickets(they were hand written replacements) and we'd never see that group again. Several times the people would argue that they had purchased the tickets from a ticket broker in the Stockton, CA area. Most had driven at least 100 miles and they were either seated elsewhere or be asked to leave, I don't know. I guess the first folks realized they were never going to be able to use the tickets so they offed them to an unsuspecting out of town regional ticket broker.
