Police came to house

Today, an officer came to my house and informed me of strange internet activity and that it was reported I'm on a few data branches. The activity was (I believe) an edgy tik tok account that I deleted 2 months ago, I am not in any trouble because I obviously didn't do anything irl but I'm a bit shaken up and was basically just told to be careful. What further steps should I take regarding this info?
