Well...sure....no harm no foul, but what always happens is that every user who now knows about this will have to run a full scan, which I did for years and it takes about 18 hours cuz I have a lot of crud in storage...
I like to look tha variant up and see if they have the code and a clue to where it is....then I look for it.
This one for example can be found at the end of the page code or where ever they stuck it. It’s at the tail end....looks like this.....
[infected_site]/in.cgi?[number_for_infection_campaign] .
There is no point in doing a full scan just for viewing that jpg, but I bet that many Freepers visit the sites that host hotlinked images to get more information about the thread. I often do.
