>>7 lol noob
"sup 4chan" is the original (or at least more original). "sup 20721" was the one obviously Enhanced Using Adobe(tm) Photoshop(tm) Software. I can tell from some of the pixels and from seeing quite a few shops in my time.
Remember what was going on at Trolltalk at the time... that was when we were at war with Mercatur. (Trolltalk has always been at war with Mercatur) Nobody ever confessed to doing the shop but it could have been Slashpanda (more like Failpanda amirite) or one of the other Mercatur fanboxen. That was when we had destroyed her guestbooks several times over and the Cracky vs Mercatur battles were at their peak.
BTW the "mercatur" account on Slashdot (that she's even posted to TT with) is actually legit; I was surprised as hell, but I have proof or STFU noob.
