I did try looking for "AFAICR" here in the forum but I couldn't find him.
I'm not sure if you're joking but I think AFAICR means As Far As I Can Recall and not an username. 
I also remember this script. AFAIK it was a chrome extension (which is open source) and I remember taking a look at the code to confirm it was legit. I can't find it right now but I'll make sure to take a look later.
