Players thinking about entering the portal (or people close to them) should be allowed to reach out to programs in a casual and unofficial manner to gauge interest.
Once a player puts their name in the portal, they effectively give up their scholarship. It can be a terrifying thing to do when you have no idea what kind of interest there is in you.
If you start cracking down on kids who are unhappy and hoping to go to a place that is a better fit, or on the schools that they desperately want and need feedback from, you are undermining the whole movement to make it easier for players to switch schools (like coaches can).
Tampering is when the schools reach out and make initial contact. IMHO it is a very different situation when a school responds to a theoretical question regarding interest from a player who wants out from their current school.
i would rather allow players to reach out before entering the portal than force them to make life changing decisions completely in the dark.
It is the right thing to do. If you are going to make changes to make it easier for players to find a place they will be happy and thrive, give them the ability to make a relatively informed decision.
