Svlad Cjelli I can't believe that you're using Hillsborough as an argument against safe-standing - that's a frighteningly simplistic and ill-informed view that has been thoroughly discredited, and one which virtually nobody subscribes to any more.
If you really think that's a valid argument I'm afraid I don't accept your claim that "you have plenty of knowledge"
One seat / One Ticket / One Persons space etc.....
From personal experience, and on top of any other argument put forward, i have personnally snapped my cruciate ligament, and torn my cartliage when Reading played Bournemouth down at Dean Court in 2002. Butler scored if i recall correctly to equalise, everyone rushes forward, i get pushed, down a step and snap, and pretty much brings my refereeing career to an end.
It is not a case of just having a set number of people into a terraced area. These people jump around / surge etc etc and right or wrong, those days at modern games and grounds are at an end.
