Is it possible to deter AI scraping by providing overly large robots.txt?

Posted by jpluimers on 2024/11/18

An idea: [Wayback/Archive] Jeroen Wiert Pluimers: “@ruurd @mcc … Maybe place useful content below 500 KiB and serve a file at least 1 GiB size?…” – Mastodon

@ruurd @mcc probably not, although Google Search limits them to 500 KiB.

developers.google.com/search/d

“Google currently enforces a robots.txt file size limit of 500 kibibytes (KiB). Content which is after the maximum file size is ignored. You can reduce the size of the robots.txt file by consolidating rules that would result in an oversized robots.txt file. For example, place excluded material in a separate directory.”

Maybe place useful content below 500 KiB and serve a file at least 1 GiB size?

It was in response to these earlier toots (with quotes of some very interesting links on when cookies are (dis)allowed –  TL;DR: it depends on local regulations):

Quit Nested SSH Sessions: use one more ~ for each nesting

Posted by jpluimers on 2024/11/18

Never too old to learn:

  • [Wayback/Archive.is] Quit Nested SSH Sessions

    works with ssh as well but is much simpler: press as many ~ as level of nest before . (by default, ~ is the escape character while . is to terminate ssh).

  • [Wayback/Archive.is] How can I break out of ssh when it locks? – Ask Ubuntu

    Notice that because hitting ~~ causes ssh to send the ~ instead of intercepting it, you can address N nested ssh connections by hitting ~ N times. (This only applies to ~s that directly follow an Enter.) That is to say that Enter~~~~~. terminates an ssh session 5 layers deep and keeps the other 4 intact.

So this is basically an extension of my 2017 blog post OpenSSH Escape Sequences (aka Kill Dead SSH Sessions) – The Lone Sysadmin (:
