alt Hacker NewsThere used to be bots that would do this automatically, but they seem to have fallen out of favor due to the high rate of false-positives (user from Subreddit A posts in Subreddit B and gets automatically banned by the automoderator on Subreddit A).
They implemented a change recently where users can make their profiles private which seemed like a cool idea to prevent this sort of thing, but in practice it is used almost exclusively by bad actors.

Just delete your old comments...
I learned a simply truth about social media. When you answer a person in a discussion, are you answering the person or the world?
When you are answering the person, and the person has seen your response by time or counter answer, there really is no need to keep your post alive beyond a few weeks.
By then the topic is already on page 10 and only of interest to google / bots / AI.
Is this a problem for the future? Not really ... if the answer is important like i want the world to keep seeing it, you keep it undeleted.
If you did a product review, keep it alive, but just answer people, or having discussions that have no relevants a year from now, just get rid of them.
But lets be honest, most of our answers are often discussions and not some deep zen state thinking exercises that everybody needs to see years from now.
The world has not gotten better and your faced with a dilemma. Reject social media totally and avoid all the mess of people using your past post history, bots and AI/LLMs eating your data non-stop, or potential profiling. Let alone if governments change...
Or use this trick ... there really is no perfect answer and you do what you feel is good for you.
