Here are the Bylaws, in case anyone is wondering.
13.1.1.3 Four-Year College Prospective Student-Athletes. An athletics staff member or other representative of the institution's athletics interests shall not communicate or make contact with the student-athlete of another NCAA Division I institution, or any individual associated with the student-athlete (e.g., family member, scholastic or nonscholastic coach, advisor), directly or indirectly, without first obtaining authorization through the notification of transfer process. Before making contact, directly or indirectly, with a student-athlete of an NCAA Division II or Division III institution, or an NAIA four-year collegiate institution, an athletics staff member or other representative of the institution's athletics interests shall comply with the rule of the applicable division or the NAIA rule for making contact with a student-athlete. [See Bylaw19.1.3-(f).] (Revised: 1/10/91, 1/16/93, 1/11/94, 4/26/01, 4/29/04 effective 8/1/04, 4/29/10 effective 8/1/10, 10/30/14, 8/8/18effective 10/15/18, 4/28/21 applicable to transfer student-athletes seeking eligibility during the 2021-22 academic year).
13.1.1.3.1 Notification of Transfer -- Undergraduate Student-Athletes. A student-athlete may initiate the notification of transfer process by providing the student-athlete's institution with a written notification of transfer and completing an educational module related to transferring. Notification of transfer must be initiated during a period specified for the applicable sport (see also Figure 13-1). If notification of transfer is provided during a specified period, the student-athlete's institution shall enter the student-athlete's information into the national transfer database within two business days of receipt of a written notification of transfer from the student-athlete or receipt of confirmation of the student-athlete's completion of the educational module, whichever occurs later. [D] (Adopted: 8/8/18 effective10/15/18, Revised: 4/28/21, 8/31/22, 9/21/22, 10/5/22, 2/2/23 effective 2/27/23, 10/4/23, 4/18/24).
Two interesting notes...
The use of the word "shall" strongly indicates the university "must" put the student athlete's name in the portal within 2 days of notice of transfer and the university has no discretion/option to do otherwise.
Even "indirect" contact through non-staff members, friends, families, advisors, other/past coaches, and other "individual(s) associated with the student athlete" is impermissible. So a lot of the categories of communications some people seem to believe doesn't constitute tampering is, apparently, still tampering (albeit much, much harder to prove).
