Can someone explain me why the Russian search engine "Yandex", is indexing the pages of user accounts (it shouldn't do it, at least for privacy reasons) and instead is slowly removing from the index the threads and posts saying that they are not "Canonical"?
Is there anything I can do to prevent this but the exact opposite?
Search engrains index User Profile Pages. The profile page is a public page, so they index it. wpForo has an option to disable profile page indexing. You can disable it in Dashboard > Forums > Settings > Features Tab. The option name is "Enable User Profile Page indexing".
You can find a profile page url in the image of the email received by Yandex annexed to the first post.
The Option is enabled from two / treee years, the post of the url added by Yandex if of two/three days ago.
Thank you very much for the report and the explanations!
If you allow me, I suggest you to expand the explanations in the online documentation because everything you have written about these commands is practically zero.
Even the link "wpForo SEO" leads to a page where nothing you have explained now, here.
Therefore, those who use the Yoast Plugin are allowed to think that the forum's SEO options are simply redundant and useless and only risk slowing down the site.
Instead from what you have explained here comes to wonder why you have given users the ability to disable these two options that according to what explained here and now seem to be totally useless but even dangerous if you disable them.
But I have one big doubt that I need to confirm:
Are we sure that after activating the SEO functions of the forum, messages in password-protected areas (beta tester of products and software) cannot be indexed in any way by search engines? There is confidential information that must not be circulated at all.
