@Ramhound you may want to click the link. He refers to an answer he posted that was deleted by DavidPostill

@KamilMaciorowski Yes, given that it is site-specific, the chance of it being malware is slim to none, especially on SuperUser where the poweruser is visiting. If it happened on every site, then I would know it was on my system, or my browser. But given that it only happens on Stack Exchange sites, it was quite obvious a feature on this site. Sorry, I don't know how else to explain, if you still don't get it. Malware targetting a specific site just is a huge waste of development resources, because the chance an SE user gets infected with this malware is slim.

Why on earth would malware specifically target SE? That just makes no sense. Especially given that SE is a site for the power user, where most users will be able to understand and deal with spyware.

@BloodPhilia thank you very much for this addition. This was exactly what I was hoping to learn. :)
