I am speaking from experience.

The latest example of that I encountered had a blatant logical inconsistency in its summary, a CVE that wasn't relevant to what was discussed, because it was corrected years before the technology existed. Someone pointed at it.

The poster hadn't done the slightest to check what they posted, they just regurgitated it. It's not the reader's job to check the crap you've posted without the slightest effort.
