What about a situation where say someone who has a perfect memory, reads it, and regurgitates it word for word or even close enough to get the same meaning across?
The problem I see with once you've published something public - whether you've deleted it or not - is if and when they reference it (especially if it's older) in part or whole -- is if they reach out to ask you if since posting/writing something, if there are any comments or updates to it, so they then post that inclusion.
Perhaps your knowledge wasn't as evolved, therefore your understanding wasn't to conclusion - which is what the process of learning is all about. Perhaps you were going through a difficult time and you revealed things you're embarrassed about, and you have a fear of ridicule or other. That's where understanding and compassion then hopefully kicks in with the reader. If you can understand these processes yourself, and be able to forgive yourself and therefore others - or forgive others and therefore yourself - then great. If worry is strong and remains strong, then perhaps the solution is developing self-awareness to understand the nitty-gritty and nuances of emotion, to help understand the worry, where it comes from - and developing the tools and skills to help them settle.
Edit to add: You'd be surprised at what people deal with on a day-to-day basis or what they had to deal with in the past. Suffering, especially emotional suffering including discomfort and fear, is a strong teacher - it's something you have to develop to be open to - otherwise the ego mind will learn and want to logically control a situation, vs. managing it - which comes with developing self-awareness, therefore better self-control, and better self-regulation.
Where I'm at in my life, on my path, I currently fluctuate between having difficulty coping with chronic pain that I have to manage which affects my executive function and decision making, and between being very suicidal; most infuriating is that I have had success with healing some of the pain with stem cell injections, however for unreasonable/irrational decision that was made, I've been blocked from getting more from the doctor who first did them - and that has cascaded into making it challenging to find another doctor to continue them, I've come to the conclusion that our health-"care" system is very broken, and which I could go into the nuances of from my experiences, however I won't in this comment.
Yes, there will be assholes who will judge me for sharing that and think negatively for that, and they are people haven't developed those skills and understanding or compassion - at least not yet, or perhaps never, however we can forgive them for that - their genetics and life path, the environment they were born into wasn't up to them.
