I looked at SPN and SGA fic, fandoms where I stand a chance of recognizing names even in het/gen/ff.net circles. I didn't recognize any, but googling led me to an LJ for one person. I think perhaps they have been promoting themselves on ff.net forums and drawing from a completely different iteration of fandom than I'm (or most anyone else posting on DW) are familiar with.

I doubt their scraped, I'm assuming all accounts are real.

From the FH Wiki post, it would appear that they pre-date fanlib and have already been around the block on being conflated with that debacle. I'm taking them at their word that they are fans as well.
