Punished for what? After reviewing the page, he produces no incentive or inducement to anyone to attend any particular school. He doesn't even directly attempt to dissuade anyone from picking a particular school. Can you even identify him has a booster as specified by NCAA standards? Which school is he aligned with? Panthers? Hawks? MN? Wisconsin? He is at liberty to add anyone as a friend he so chooses. My recommendation would be to stop the hysteria and simply ignore him. Why even tread onto his page? Good luck with the law thing!
All of your electronic contact with Prospective Student-Athletes (PSA's) are logged by Facebook and can be subpoenaed. The same goes for all of the identifying information you have posted in support of the Iowa Hawkeyes.
The standard is not whether you provided any "incentive or inducement" to attend any particular school. The standard is: (a) whether you are a "representative" of the Iowa Hawkeyes; and (b) whether you have encouraged participants to select the University of Iowa and not the University of Minnesota. Whether you have provided improper benefits is a completely separate standard, and separately actionable from providing basic encouragement.
"Representatives" of the University of Iowa are defined broadly to include both paid and unpaid persons formally recruiting on behalf of the athletic department, AND anyone who has ever contributed financially to the athletic program, for instance through being a season ticket holder. You are a "representative" if you ever contributed money, even if you haven't in many years. The rule is "once a booster always a booster" for obvious reasons. The definition is actually broad enough to include those who have not actually contributed money, but this is one way to make the designation automatic.
As for providing "encouragement," I have personally seen your direct contact with PSA's on your Facebook page and "negative" recruiting against the University of Minnesota football program. These are not generic posts to the public at large, which may include PSA's. These are direct contacts to known PSA's being recruited by the University of Minnesota. They are interwoven with posts praising the University of Iowa, for example by claiming Iowa CB Amari Spievey is "watching film" when chastising Gopher players on Facebook who post that they are hanging out with their friends. It also includes your multiple posts praising Iowa and its coaching staff for turning out NFL draftees, which you call "Iowa millionaires."
It may be that a school currently does not have the obligation to police the Internet to stop all of its "representatives," but that is a burgeoning field of exploration for the NCAA and compliance departments. Certainly schools are held responsible for the secret activities of their boosters in support of recruiting; there is a strong argument that schools should be responsible for public, violative conduct by its boosters.
The obvious box this opens is the expanse of the Internet and a school's responsibility for policing boosters on direct-contact social sites like Facebook and Twitter. One can see the wisdom, however, in cracking down on grassroots booster activities aimed at poisoning the recruiting efforts of their conference rivals, while promoting their own school publicly to the same, targeted, group of PSA's. One of the benefits of the Internet, however, is that direct contact, including the who, what, when, where, and how, is provable, unlike encounters with PSA's elsewhere. In this case, Iowa's compliance department will definitely be given notice of your direct contact with PSA's and recruiting efforts on Iowa's behalf. There will be no claim of ignorance.
You are not helping the University of Iowa football program with your direct contact with PSA's on the Internet, Pantherhawk.
