My youtube account was hacked

I created a video archive account on YouTube and it had an extremely long and difficult to guess password.
I even had a two-step verification, but on Friday the 13th I got hacked by a freaky hacker that uploaded 100 copies of this one video called "watchful eyes".
I was unable to access my account but I could watch its contents without an account.
It started with a slightly red head without a face sliding on the screen. Two red eyes would go in any direction as the head stopped moving. The man whispered.
I watch you all
I am the internet
I am everywhere you look
Hiding your webcams will not work
As I can see you from all cameras and all angles
I contacted YouTube via email about the situation. They locked the hacker out and I was able to rejoin my account. I deleted most of the spammed videos except for one for archiving purposes.
But I don't think I will ever use that account again. It only contains that one hacker video, but whatever. I would rather be safe.
However this hacker did indeed scare me, and sometimes I feel like he is still there somewhere roaming in my house as I swore that I saw him in the corner of my eyes or I heard someone walking in my attic.
