Which they don’t respect. I’ve had it for my blog for years and they still added it to wayback machine, see my last comment for their official announcement of the ignore robots.txt policy, it is not new.
I wonder how archive.org_bot behaves when <meta name="robots" content="noindex, noarchive, nocache" /> is present.
Just out of curiosity, why don't you want your public blog archived? not questioning, just trying to understand the logic/motivations?
Also, I think you're being unfairly downvoted.
