Yandex advertised with the phone in contextual ads

Recently, I tried to start a new advertising campaign on Yandex.Direct. Compiled the text, picked up the keywords ... But the ads were not moderated, because they violated some rules. The rules in Yandex, as I understand it, are taken very seriously. There are certain requirements for the quality of sites, the content of ads advertisers.
One of the Directive rules prohibits the placement of advertiser’s contact information in the ad text. This is logical, since the visitor can simply see the phone and immediately call without following the link. Imagine the savings if a taxi or pizza is advertised to your home. It’s paid only for a click on an ad ...
And this is how Direct itself is advertised in other contextual advertising systems.



The ad I found in Google in the issuance of the phrase "contextual advertising." Yandex had several ads there, one of which with a call-center telephone. Before publication I looked, it seems to be gone. Maybe banned? :) But all the same, it is clear if some small firms with a limited budget would "hack". But Yandex - the leader of the search market Runet. Is it really that bad with money?
