I've actually been meaning to post about this as well. I recently went through and re-added my entire vinyl collection to Discogs, and was surprised to find after careful consideration that a couple of my EBW copies are in fact bootlegs. I can't remember off the top of my head what else gave it away, but comparing mine to the descriptions on Discogs I was pretty confident a couple of mine were boots.
On that topic, although maybe it should go in another thread, I found I had a couple other Chems bootlegs that I'd assumed were legit. For example: I have a bootleg of TPPR 12". The labels are slightly different and it came in a generic sleeve w/ no poster. Seems like an odd choice for someone to make a fake of, as opposed to say BRB or HBHG.
