Jet Airways in Ban period from 14 Nov 2018

Jet Airways in Ban period and Zerodha Not allowing to place order but I can see there are lots of buyer and seller in calls and put , Can some one help to understand this how people are placing order if this is in ban period .

those who already hold it are doing the opposite trade (square off)

plus some punters can do trade with penalty paid to exchange (retailers cant do it) - This i heard somewhere i am not sure
