New GTX 1080 not responding!

Got problem here
My GTX 1080 to much not responding!

You might want to start by telling us more about the problem. I don’t think anybody is going to open a random PDF which may well contain malware.

This is actually spam. The picture is some sort of an advertisement for a movie streaming service.

The $64K question is: Is that kind of spam injected by an AI-driven bot, or by some poor fool somewhere?

A novel (?) spam technique I noticed being used on a different site is to repost the content of an exiting posting (so the content looks genuine and topical for the site) and insert the spam link into that.
