Can you get hacked just because you accepted a team invite?

Maybe a stupid question, but idk… So i started RL today and was met with a party invite from “Pulse.Mizu”. I accepted, thinking that he was one of my friends and was met with the message “1vs1” in the party chat. After I asked him who he was, he didn’t respond so i left and got 2 more team invites immediately. I’m worried. I blocked him but don’t know what happened/what to do now.
