Long ad in the middle of the article:

Adguard Base Filters
Firefox 64.0
uBlock Origin 1.17.4
Fix:
techspot.com##[data-hide="#ad_rectangle"]
I don't see this element.
@Alex-302:
The ad container is still there, because the rule that I created shows up in uBO's logger when i visit the page.
It's probably just not used at the moment.

Yes, that element is still in their source code, even though it's currently not being used.
please upload saved full page
<div style="display:none;" class="tshoop" data-type="zadbl_news_single" data-hide="#ad_rectangle"></div>

style="display:none;" so hidden by webmaster?
It is empty

I asked about saved page, not source code(Ctrl+S)
That's what @THEtomaso and I said before. It _is_ empty, but since it is still in code, they may have just removed it temporarily.
Also, there is this one:
techspot.com##[id="billboard_placeholder"]
..but I haven't actually seen it used.
