I don't know how common this type of "cheating" was in 2.0. There were a couple times where I noticed a D3 team that was recruiting nationally and consistently getting guys with high-highs in the right places, where it looked awfully suspicious. But for the most part, I didn't worry about it too much. I don't worry about it now, in fact. As far as I can tell, it will take a little more work to "cheat" the discovery process in 3.0, and it's actually not a big payoff. A guy worth getting is probably going to be spotted by others, and recruiting at distance in D2/3 is still pretty tough in 3.0. Even if the guy wants to play far away, a local team can go all in, the distance team can't, and will likely get beaten. I suspect most coaches who try to game it like this will find it's too much fuss to be enjoyable, and will burn out.
And as ever, I'm sure we will have citizen police raising red flags when they become apparent.
