is sn gone for good?

So i was just wondering what happened to SN? I know they were in homecoming and stuff but i havent seen or heard from them at all outside of that, before or after, even when i go to parties with KAs ATOs KSs or KKGs i know a lot of them have no idea and some even told me theyre suspended?? When and how did that happen??

If not then where have they been the assed 2 years because no one has done anything with them.. my younger brother is from columbia and wanting to rush them since our grandpa and uncle were SNs at bama.
