I wonder what is causing the automated summary to display such a wall of text, including non-relevant data like advertisements and author lists?

I tried posting the same link to an unrelated community that I moderate, and the result was the same - all the unrelated stuff was retrieved, with no way to enter a decent summary. :o

In my opinion, the summary should help the reader determine if they want to read the article / watch the video, so we need to find some better solution than the current way it behaves.

Is it OK if I refer this topic as a sample to u/poVoq (our local server admin), hoping that they might know useful tricks?
