I think text withing blockquotes should be highlighted.
Blockquote tag in source present,
and firstly, text meaning says about this.

the reason why they not highlite blockq., is just bitrix normalise css.
as you can see on screnshot above.

Other pages with blockquotes not higlighted:
http://krasnoturinsk.info/novosti/putin-priexal-v-ekaterinburg-i-otchital-kujvasheva/
text says: "main theme of russian."

http://krasnoturinsk.info/novosti/proizvoditeli-prosyat-pravitelstvo-uskorit-rost-cen-na-kolbasy/
they use id here "dfp_banner_mobile_billboard_1" within.


So such texts should be highlighted in any way, because they are qoutes.
so pleas dont say more "they copypasted from other site".
