OK, this is the question I have.
This picture is taken from the OB side of the fence. The other side, with the basket, is in bounds. Is the disc OB? It's on the fair side of the chain link, but the disc pushed the chain link out as it stuck between the top rail and the chain link. But it is on the OB side of the top rail.
According to 808 QA 10, the fence OB line is a flexible OB line. Although the question addresses a different scenario, I think the principle still applies. My argument is that the OB line flexed with the disc wedging itself, so the disc is in fact fair.
Argue away.
