Getting weird LinkedIn DM's

Lately on LinkedIn I've been getting DM's from random men in my uni. Some will ask me out or will ask me where I live. Some will try to ask about my internship experience, and if I reply, they still start flirting or will just ghost me?? Here are some of the messages I have received in the past week:

Hey ___, I wanted to say as I saw ur connection request come in i took a look at ur research on your profile and it looks super interesting! Funnily enough I’ve been heavily considering pursuing research and some project work with materials development so ur experience seemingly w it caught my eye. Thanks

Hey ___, I know this is random, and I am sorry for asking if you’re already with someone, but you seem really cool! Although we haven't spoken before, I believe our interests might be similar. It would be great to talk further and grab coffee sometime to get to know each other better if you’d be interested!

Okay.

Did you have a question or something you wanted us to answer? I'm not sure what you're looking for from this thread based on your OP.

are you seeking advice or complaining - hard to tell
