Scarlet200% said: It was mentioned that some people go over just the thumbnails and only expand the image if they deem it worth looking at closer. While it obviously doesn't apply to everyone going by this discussion, is it potentially not a problem in itself?
Yes and no. If I see five tentacles raping the hell out of a girl in the thumbnail, I don't need to view the full image to know I would absolutely never approve it under any circumstances. Also, if I check out a couple pages of a doujin and decide not to approve it, I don't need to then open up every other page of it to know I'd hide it.
When I was going through the entire queue, I would very quickly skim rating:e and hide almost all of them based on thumbnails.
rating:q would get a much closer look after I weeded out the obviously excessively sized breasts and such.
rating:s would get a full image view for virtually everything.
Basically, the thumbnail tends to be adequate for determining the broad subject matter of the image. Judging the finer details of stuff that isn't an automatic pass should require checking the full size, yes.
