I’ve been trying this for a number of years now. Unfortunately I was a foolish child born in the late 90’s so wresting control of my personal information from the dozens and dozens of services I blindly gave to has been challenging.
When I first got online in the late 90s I was “default closed” and never associated my online persona with my IRL identity. At some point in the mid 2000s I made the conscious decision to the “default open”; to use my real name everywhere, not use private accounts etc. I gradually moved some of the public content from other platforms onto my own (hosted) blog, and then moved to a VPS for my blogs and other stuff like private git repos.
In the past few weeks I’ve switched back to “default closed”. Unlike the OP, I’m not worried about how I can keep sharing things publicly - for the most part I’ve decided to stop doing that at all. I’ve taken down my blogs, made my social media accounts private, hugely culled friends and followers, closed a ton of accounts for platforms/services I don’t use.
Large parts of the last 15-odd years of my online life are still available with a bit of effort, but it’s gratifying that now you have to put in a little more work than simply googling my name.
Same here… It’s very hard and even with the recent GDPR and right to be forgotten it’s still challenging to do anything, because:
Although, I do understand that having a way to retrieve every service that you resisted to would be handy but a real security issue…
In the end, I’m not trying as the author to self-host everything, but to be conscious about which data I hand in to which service. To me it feels like many things in life, making trade-offs.
