Hope you can get this behind you soon. Just so you know, they can and do delete steem accounts, too. I doubt yours is in danger but I was pretty bummed when this happened: https://heavy.com/news/2019/01/the-dark-overlord-update-banned-steemit-twitter-reddit/
It also seems you can get it voluntarily deletted:

I thought the blockchain was "forever" but honestly, I cannot even find my own posts if they are more than 2 months old.
This is a problem. My understanding is that (our) posts are stored on the STEEM blockchain, but if the condensers like Steemit can decide what to show or not show. Are there any tools to search and view content on the STEEM blockchain, even stuff that's not visible on the main condensers like Steemit and Busy?
I am really not the person to ask. As I said, I cannot even find my own posts after about 2 months.
