The easy solution to this, is take a picture at the end of the game (or less than a minute to go) of the student section like has been posted above. Count then number of students in that block at the end of the game. If the number of students in that block is less than 75% of capacity for the block, then they get knocked a damaging number of "spirit points". What defines a "spirit point" more, than having your butt in the stadium big win/big lose/draw???????
As for students/pledging cheating the system by scanning a bunch of ids at other events and then leaving, they need to fix that problem and stat. Have them pick up a card at the beginning of those events. At the end of the event, let them turn the card in for the privilege of scanning their id and their id only.
Lastly, pledges or whomever else trying to reserve a significant number of seats in the general student section is BS. That crap needs to end. I'd have serious problems with that if I were a student still.
The problem Auburn currently has, is they've let these fraternities run amok and abuse the system without any repercussions. That's the bottom line. AU needs to get control of it.
