Well it isn't for everyone else. Perhaps you don't care much for the no undrafted players rule, but I think a lot more people do, and we do live in a democracy.
I see what he's talking about, another example being people with usernames dedicated to players(the most obvious example isn't alone either, my last username was no better), it is kind of funny. I have no issue with the rule at all, I even like it there, despite my own opinions that it does very little. Really, allusions, any allusions, are just as worse, and even worse yet is when people speculate on the value of said undrafted(I've seen it happen many times). If I remember right, someone(can't remember, and wouldn't say if I did) did that and it actually affected the draft.
Not that I'm saying to get rid of the rule, it's very helpful and makes things much simpler, especially when you get used to it, but I do think some are going overreacting when they see it. A nice PM or even a post on here to remind them is fine enough, even for a repeat offender(it really does take some getting used to, especially when posting bios and other evidence). No need to go crazy.
