I'm sure everyone is aware of the massive amounts of lewds Holomembers have, as well as the discrepancy between the quantities of material for different members. Therefore, I thought I'd put it into perspective by noting down the number of lewds for each member. I'll be using three sources for this; pixiv(R18), rule34.xxx and danbooru(rating:explicit), which are the main sites I personally use. The format will be: name:[pixiv]/[rule34]/[danbooru]. Nobody cares about Holostar lewds so I'll be skipping them.

Now, obviously, there are errors in this method. Firstly, in pixiv a lot of posts may contain multiple unique images that aren't counted separately, unlike in rule34 and danbooru, therefore the actual number of unique pixiv images is much larger. For example, there are posts with dozens of pages of lewds for Mio and Botan that will only be counted once, even though they're all unique.
Additionally, there's the problem with tagging. This is true for all three sites, however in pixiv especially, specifically for the ID/EN gens, tags are inconsistent. Some posts are tagged with the name in English instead of Japanese, and some posts aren't tagged at all. Therefore, again, the actual number of lewds is larger.
There's also the problem of posts that are only on twitter/other sites, obviously not all of those would be uploaded in one of these sites (and vice versa), thus there are definitely more posts than what I've written above.
Some of you may ask "why include rule34 and danbooru". The main reason for this is that there are posts in those sites that have not been uploaded to pixiv. They may not be a lot, but they are unique and can be of good quality so I felt I needed to include them. For rule34 specifically there is another reason, which you may be able to infer by looking at EN again; a considerable number of lewds are uploaded there instead of pixiv.

Next post will be rankings using the highest number of the three.
