Aged account flagged?

Hey everyone just a few questions regarding an account be red flagged or black listed for buying views.

I have a feeling my channel wont hold rank anymore because I had used botted views, likes and comments in the past.

1: is there any way to know for sure that its been black listed?

2: if I use another account I have had for a while to upload will youtube know I am the same person because of the same ip?

Just want to figure out what my next step should be… I either use this old…
