CSR approached me during boarding and informed me that first class was booked to XX passengers so she was going to have to give out one of the blocked seats; either X2 or X5. I told her it was my understanding that X2 is blocked for my personal social distancing and that X5 is blocked for FA #4 or a cabin jumpseater. Therefore; so long as there wasn't anyone jumpseating and we didn't have the 4th Flight Attendant that X5 would be the wiser choice. She then assigned X5 to a passenger. I was then told inflight by one of the deadheading flight attendants that because it is blocked for jumpseat purposes; it violates an FAR to allow somebody to sit there.
Flight Attendant reported a blocked jumpseat was subsequently used possibly violating FAR rules.
