I know what you mean ~ I usually do look to see where a troll's posted image originates, but my reaction to those images yesterday was to simply hit the abuse button and not look back.
I had the same reaction, but I went into my temp. Internet files after the fact, found the images and posted the links yesterday...not sure where exactly in this thread but fairly early.
Yeah.
I checked to see where he was linking from the one day in the Canteen.
That was, I think, his second hit on the Canteen.
Anyway, I looked at where the link was going to get the image, and it was a spanish language blog.
And I didn't think to keep the link to see if he used it more than the two times I am aware of.
