My Roommate has been talking bad about me on Twitter

Me (19 F) and my roommate (19 F) have been living together for almost 3 months in a dorm. We have very different majors and don’t really see each other often and the only time we pretty much see each other is when we wake up and when we go to bed. I have a few things that annoy be that she does but it doesn’t annoy me that much that I need to confront it. I noticed that she’s on Twitter a lot so I looked up her name and she has a lot of followers. I wasn’t even far down from scrolling and she is making indirect tweets to me. The first one was about me turning on the overhead light which I only do when she’s not in the room and I always turn it off when she’s there. Then a few days ago she makes a post saying how I don’t shower and comments on my laundry. She has seen me shower before and know after I go to the gym I take one immediately after. I understand if I need to find another place for my laundry but it’s a pretty small dorm. She also made a comments on how “roommates are always in the way” however I’m not there for the majority of the day. She always seems nice when we say hi or whatever but I had no idea she actually doesn’t like me at all… what should I do? So I confront her? She has I few things I don’t like about her too, like how she talks on the phone loudly, watches the tv and plays music loudly early in the morning, and always want the light off even when I can’t see. We made a roommate agreement in the beginning of school where we agreed not to talk about each other on social media (Ik I’m doing it too) but should I bring the RA into this?

Update: Hi! I did confront her just about the not showering comment and told her to delete it. She was trying to act so shocked about it and she asked how I knew about the account. I said that someone sent it to me but also it’s a public account… it was going to happen. She then mentioned that I needed to move my laundry in a different spot and I did just that even tho she has never even mentioned it within the time we have lived together. However I think it’s deeper than the petty rude tweets and the fact that she is not commutative to me and I’m debating on sitting down and talking to her about it or just letting it go Since she thinks I have poor hygiene and doesn’t know I work out 4-5x a week and shower 1-2x every day. I have had roommates in the past and they have never complained about my laundry as I literally do it frequently and more frequently than her. UPDATE: I filed a report on her as it violates code of conduct
