With the current adjusted procedure for flight attendants to sit in cabin seats for takeoff and landing; as 'X' I was occupying seat XD. Shortly after takeoff I realized my seatbelt was twisted and upon closer inspection I noticed that the safety pins were missing at all 4 attachment points. I notified the 'Y' and she assisted me in doing a spot check of the cabin; randomly checking between 30-40 seats. Not a single one had the safety pins installed on either of the 2 attachment points. I notified the other FAs and the Flight Deck. Many FAs wouldn't even know to check for this; I just so happened to have watched Tech Ops replace a seatbelt and saw the safety pin. It is alarming that an entire aircraft could be dispatched with what seems to be 100 NON-compliance on this issue...it makes me question what else it not installed properly.
Flight Attendant reported sitting in a passenger seat and checking the seat belt; Attendant noticed the safety pins were missing.  She and another Flight Attendant checked other seats to see if they also had safety pin which they did not.
