9 year creator as well, and I was legitimately sad when I pressed that delete account button. Before running the automated removal scripts I read through each one of my posts and comments and that brought back a lot of interesting memories of a different younger me. I archived what I could and got rid of the rest.
Yes I use third party apps but it's the whole response from /u/spez and Reddit that really made me call it quits. They're clearly catering for the Tiktok generation and not users who genuinely want to post original content and build good communities.
