It happened at the first Seagulls v Palace Amex meeting - a fan got banned after confronting some rather vocal Palace fans in the 1901. Can't remember all the details but there were threads about it at the time.
There were plenty of Albion in both hospitality areas at Selhurst. I'd be amazed if there are no Palace in our areas today.
You appeared to have a "section" of your own though right by the Brighton fans.
You will be reported and face a ban. If you must associate with such types, leave them outside.
I think that is taking this 'rivalry' far too far. There's often opposition fans in the 1901. You can support someone else without being a hooligan.
Indeed, so the club have learnt their lesson. Any Palace fan being obviously Palace (knuckles dragging on the ground, reading caravanning weekly etc) will be removed and member banned.
What a ridiculous caricature of Palace fans.
As if any of them can read!
