Yes... 13+ years on Reddit on my main account (different name than my Lemmy account), and it's gone. I've deleted all my posts and thousands of replies. I was active in several communities, including the Linux and open-source communities.
I used a script to edit my post history and replace my posts with random text, and then after a waiting period, delete the posts entirely. It took a couple of days to sift through it all. Then once I was down to zero posts... deleted my account.
