There is a problem with Yandex

Okay!

Jeff, there’s a question. I don’t know about you, but in my case, I have to create a robot.txt and prescribe rules for different bots in it, including separately for Yandex, because he considers himself particularly gifted. The bottom line is that I have set the rules that are prescribed in your plugin settings for only one bot,

User-agent: *
Disallow: /*blackhole
Disallow: /?blackhole

and I didn’t specify these rules for Yandex. Can this lead to the consequences that my sites are currently experiencing? Do I need to specify the rules for configuring your plugin for Yandex bots as well? Maybe this will fix the problem!?

Now my robots txt file looks like this:

User-agent: *
Disallow: /*blackhole
Disallow: /?blackhole
Disallow: /cgi-bin
Disallow: /wp-admin
Disallow: /wp-includes
Disallow: /wp-content/plugins
Disallow: /wp-content/cache
Disallow: /wp-content/themes
Disallow: /trackback
Disallow: */trackback
Disallow: */*/trackback
Disallow: */*/feed/*/
Disallow: */feed
Disallow: /tag
Disallow: /ads

User-agent: Yandex
Disallow:
Clean-param: blackhole /
Disallow: /cgi-bin
Disallow: /wp-admin
Disallow: /wp-includes
Disallow: /wp-content/plugins
Disallow: /wp-content/cache
Disallow: /wp-content/themes
Disallow: /trackback
Disallow: */trackback
Disallow: */*/trackback
Disallow: */*/feed/*/
Disallow: */feed
Disallow: /tag
Disallow: /xmlrpc.php

Make sure this is added to both sets of rules (Yandex and wildcard *):

Disallow: /*blackhole
Disallow: /?blackhole

Otherwise Yandex will not see it.

and what you advised yesterday, to leave?

Disallow:
Clean-param: blackhole /

Good question. Looks like a grey area. I am new to the Yandex Clean-param rule, so not sure how/if/when it should be used with Disallow, if it’s required or not, etc. Maybe reach out to Yandex (there is a link to contact on the resource you provided previously). Explain the situation and ask for their recommendations. That way you will know for sure what is the proper syntax, etc.

All right, Jeff! In principle, I planned to contact them already, since the common sense of a normal person is not able to understand the dark thoughts of Yandex. Thank you for your help!
