So I try to make a copy of any interesting web pages on archive.is these days.

VOX for example returns a 0-sized page for archive.is. In the past VICE returned 404s to archive.is https://i.imgur.com/OnFdVpS.jpg
What I mean to say is that these services are useful but they are not faultless.
In short, before you publish a blog post that is sexist/racist/homophobic/whatever, consider that even if you delete it, others may have a copy and will use it against you.
the issue I have is, we should not be able to just block access to archived content because its embarrassing.
