Weird substack post

I checked in on my substack profile for the first time in a long while. I noticed that there was this very weird post/note or something. It was basically pornographic and certainly not something that would be posted here by me. I am not sure what is going on here but I have updated the passwords to this account and I will be checking in way more often since, it was several months since I was actually here using this on my computer. Most of the time I get notifications on my phone and I read via that format. I apologize if it caused anyone to stumble or worse it was not something I would even want to be associated with. It seems to be a hack?? I don’t know really. I am really not very tech smart. Please reach out to me if this happens again.

Thanks

Turner
