Hi Grandad, we are handling exploits on a case by case basis at this point, and waiting for popular sentiment to determine those. Generally, we try to not have tons of rules because that also requires someone to police all those rules.
But with regards to unacceptable exploits, the only one that we have agreed on is the punt block one. That's too gamebreaking. We don't have hard and fast rules like other leagues that say "you must be X number of pounds to be on the DL" for example. Rather, the rule is don't consciously try to trigger an obscene number of blocks by doing something totally out of the ordinary and stuff like a DB on the DL for example. As you know, it is very obvious when someone is actively trying to do it.
But with regard to the other, more borderline exploits, or game flaws, we generally let those fly. You can play LB at DE and SS at LB if that's what you are asking. To me that's generally within the realm of things real football teams might do. And yes, we allow WR at RB and you can have WR only on your team if you really want. If folks don't like that they are free to speak up and we will look at putting in some rules, but in general, the league has been very good at "fair play" and we haven't had anyone go all out "play the exploits." Hopefully that continues, because the last thing I want to do is check everyone's roster all the time to make sure they are comply with rules X, Y and Z.
If you feel that there is a exploit that needs attention that I am not aware of (because I don't play in any other leagues, I'm often behind the curve when it comes to learning about exploits) please let me know and we can investigate and take steps as needed.
