Deleting a post is simply marking a piece of text so nobody sees it, but I think the text is still stored in their servers.
Furthermore, a large company like reddit, must backup regularly, meaning there must be several copies of my posts in several SSDs. If the backup once a day… some of my posts are 5 years old.
Companies exist to make money. I suspect they just marked my posts not to be readable by anyone, except staff and they can still monetize them.
Am I wearing a tinfoil hat way too often?
Therfor, it isn’t a great problem, tbh.
The gouverment my spyy on us just to have as much information as possible to get profiles but companies need you as possible customer. If you never use the side againt, they would not find any use of the data and to store it makes costs. So, they probable delete them after a certain time.
