@sposp - I am not certain there is much difference between this and other sample galleries, other than the fact the "creator" themself is also the uploader. As a grey area, I admit this bothers me, however. Sample galleries are explicitly allowed, but there is no coverage as to whether or not using them for self-promotion is acceptable use. Conversely, we have had at least one case in the past where an uploader was uploading his own scans, but downscaled as promotion for his own site where the higher quality ones were hosted, and that individual was made to quit it. I am not certain as to the actual difference between this situation and that one as far as the existing rules go. I am also not certain if anyone would have a problem if the artist of a given doujinshi posted their page samples here themselves, instead of a normal user posting them. We could really use some clarification about this.
@sypha I don't think I would have an issue if it didn't have 3 images repeated and 11 pages of ads for his other sets, that is nearly half this set. Also it's the same ads he puts in all his other uploads.
