Some platforms like Mastodon allow individual users to discourage search engines from indexing their profile. But, by default, as far as I know all platforms allow indexing. Lemmy seems to not provide any option to control this kind of thing so everything should get indexed.

The thing is, using “thingtosearch reddit” you’re not using any search engine properly, that’s kind of a hack. What you would do is actually “thingtosearch site:reddit.com” to limit searches to a specific site. This works with any site, of course, so you could for example do “thingtosearch site:feddit.it” (that’s my instance), and you will get specific results (which actually might include results from other instances, due to how this indexing works, even though they will be displayed from the site of the instance you specified). (I just noticed btw that DuckDuckGo doesn’t list anything for site:myinstance… well, that’s strange, Google has no problem.)

On mobile you can use extensions like uBlock Origin (content blocker) or Stylus (CSS injector) if you use some specific browsers, and use youtube.com in those: Firefox, Yandex Browser (ugh I know), or Kiwi Browser (Android-only). It’s a mess, I know, but it’s a solution.

How do you test a cable tester? Do you have a cable tester tester? And how do you know that you cable tester tester is in fact working, without a cable tester tester tester?
