They do list that since they're no "expert" it may be a "knock off" so "bid accordingly"...
(Apparently ppl have been messaging the seller it's a fake?)
That being said, if the seller has a reasonable suspicion, why not get it authenticated/do some research *before* listing it?? As you said, this is a bad fake- 5 minutes of googling how to spot a fake would suffice.
Ok, I didn't see that before but now that it's out there, hopefully nobody will bid.
