Sorry for the late report, it was not my intention, just lack of time.

This URL needs IV.

Blockquote and (internal) iframe provide the same content - link to another article on pcpress.rs.

On your template, all articles with similar content (blockquote and iframe) will not have IV.

My template handles these cases better, all relevant content is preserved and IV generated.
There are many articles like this one and there are no reasons to omit it from IV.
For example:
https://pcpress.rs/obelezen-dan-zastite-podataka-o-licnosti-nove-regulative-i-nove-bojazni/
https://pcpress.rs/ukoliko-se-trendovi-nastave-ove-godine-dobijamo-novog-kralja-pametnih-telefona/
etc...

Yes, iframe has image and text, but related blocks also have images and text and displays without its.
