If you bunted home a run against me with Arky Vaughan I'd have a fit also. Actually, I'd just leave and let the remaining games sim. If I don't want Arky to hit in the 8th, I'd probably pinch-hit for him. If George Scott is at first, I'd run for Scott and then hit and run. Problem is everyone has a valid self-interest point, and WIS isn't going to fix it any time soon. You want to bunt to avoid a DP; dahs, szcz and I would rather take the chance of a DP rather than (take your pick… exploit a flaw, do whatever is needed to win, tick off other owners, whatever). Knowing that people get angry about it, those who bunt should not be surprised when people, um, get angry about it.
And if by "that is a form of IF in" you mean letting the game sim instead of playing live, that's exactly my point. If the theory is that the bunt is fair game when the IF is not in, I can either let the games sim most of the time or cut back from 20 or so live teams at a time to 4 or 5 so I can pay attention to every at-bat. I don't think anyone trying to fill leagues wants me to cut back to 4 or 5 teams, but I could be mistaken. There is, after all, a first time for everything.
