I had the same reaction when one of my first posts was closed. It was through that post that I first came to know many of the regulars on this board. ( @danabw ) And yet, the thread had grown to 622 entries over the years. Much of the information was outdated and could mislead a new user searching for information or solutions. (I guess it still could.)
Sadly, I had to let it go ....
But, we can always start new threads and even include links to our pearls of advice from days long ago!
