When you published your article though, you wanted people to read it. You can't blame the people around you for changing your mind. And "nothing gets deleted on the internet".
I won't blame people for storing a private copy, but I will blame people for sharing such copy if it is against my will, especially if they're claiming it is their right and thus my integrity has to suffer.
You are breaking the social contract of copyright when trying to use it as a tool of censorship. The whole underlying rationale for modern copyright was spelled out in the first country to adopt it:
>To promote the progress of science and useful arts, by securing for limited times to authors and inventors the exclusive right to their respective writings and discoveries.
We, the people, trade our natural right of copying and selling anything we see for the benefit of increased dissemination of art and science.
Your integrity is kept perfectly pristine if your work only stays in your draw. The second you publish your work it is no longer yours.
What social contract? Technically, archive.org is in violation of copyright. It does not matter if robots.txt allows it or not. Pointing people to "content" like a search engine is fine. Displaying "content" on another website is not.
Even worse is nyud.net, which essentially steals credit.
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.
