Can I get my sister in any legal trouble for this?

My sister likes to get me in trouble. Now I think I might have something on her that woud get her in legal trouble. Right now, she's cheating in school and she's on probation. Is cheating in school a violation of probation? How much legal trouble would she get into. I've never had dirt on her for a long time now and I don't want to miss this oppurtunity. If someone snitches on me, I'l snitch right back. What are the laws about this in Manatee county?
