Oh those Invaders!

OC'ers are - once again - invading FC.
Their topics are extremely annoying now considering most of them say "I'm from OC" or for example: "Yo! I'm from OC, leave us alone!"
Why won't they blend in without introducing themselves saying they're from OC causing arguments in FC?
And if their club is so 'amazing' and FC is so 'boring', why won't they leave FC and go back to OC? Hm...
