A second option is to piggyback on other services, such as github, wikipedia (some allow personal pages in your own namespace) and various message boards. You could even mail your blog posts to Swedish government services as they would be obliged to archive it. People would "access" your blog posts by mailing the same government services and requesting all emails sent by saifulwebid on June 12, 2019 for example. Of course this idea doesn't scale and if enough people tried it they would change the rules.
Usenet posts should last a very long time too. But even those eventually vanishes and posts from the 80's are nowhere to be found.
