So my ex cheated on me with one of her DS

So my (now) ex cheated on me with one of her Drill Sergeants and is now dating him. I'm not in the army, but I know she is still in IET/AIT/TRADOC. Should/could I do anything to fuck with them? Drop an anonymous tip about their relationship (if it's not allowed? I don't know much about UCMJ but I feel like Cadre/permanent party relationships and/or NCO/Junior enlisted relationships wouldn't be allowed) To the mods who are gonna think this is shit posting, it really isn't. I dated this girl for 3 years and I'm pissed. Advice?

Update: I have called and spoken to the IG at her basic training base and given all proof. I chose to remain anonymous so I will not receive a follow up, but I am sure I will hear about it in the weeks to come, and if so I will update you guys with that news.
