WIBTA for giving names to one friend group in order to sue my other friend group?

Disclaimer: Everyone involved is around college-age. I was in a discord call with one friend group (that I have grown up with in person) and I was in-person with another friend group at my house. The friend groups do not know each other at all. One friend in the IRL group (We'll call L) decides that it would be funny to turn on my discord camera and moon everyone in the call. He did it before I could turn off the camera. All I heard on the other end was "Ew, yuck, that's wild", but nothing more, and I was not worried that anything would happen since they normally can take jokes and have crude senses of humor. Next thing I know, a video of what happened gets posted to our private discord chat by one friend (we'll call him "C"), and we all laugh at it and we begin to move on. Then, one of my friends in the discord call (we'll call him "G"), decides to save the video from the chat and draft up a report to the school with the video and the names of the people involved, so that they would get in trouble. He did this because he said that it was "the right thing to do" and that he "needed to bring justice to the community", although I know that was a load of BS because he is normally the least-bothered person when it comes to gross things like that. I told him that it would cause alot of problems that he didn't want to start but he insisted on sending the report. After this, me and my friend group IRL started profusely apologizing saying that the whole thing was a dumb joke and that nobody was meant to be offended, and that things are going too far. After this, G, C, and another friend in the call (we'll call Z) began to make fun of him and harass him, and make him play games with them in order for the report to not be sent (EX: roll a dice with me and if you guess correctly, I'll show mercy). They made fun of him relentlessly because they had the upper hand and were holding this report over him, which we knew could ruin both his school career and athletic career, since he is an athlete. I asked G why he was doing this, and he said that he was "Hating because I like to hate". In the end, due to encouragement from C and Z, G sent the report and now we found out the we have to go to a student court and that could L could get kicked off of his sports team, over something so menial that I know for a fact did not mean anything to anyone involved. Now, L and everyone in the IRL friend group are asking me for their names so that if they do end up getting kicked out of school and off the team, to sue for the harassment, since they (and I) both believe that nobody was actually hurt by this, and that this is something not worth losing a career over at all. They (and I) believe that C,Z, and especially G were doing all of this just for jokes/out of malice and deserve to be held responsible for their actions if things escalate to the level of a career ending.
