New Pixiv error messages

I've seen the suspended account error (該当ユーザーのアカウントは停止されています) and the deleted image error (該当作品は削除されたか、存在しない作品IDです), but now I've run two new errors, and I don't know what they mean. Anybody have a clue?

該当作品の公開レベルにより閲覧できません。

Google Translate:
You can browse through the appropriate level of public works

Found in post #305919, post #304524, and post #306171, among others. Most posts with this error are already bad id, but the deleted post error is still in use elsewhere.

post #305973 (Gekka meaning the artist, link ). That one's a functioning artist...

Google Translate:
This work has been published only in Nasan new Maipiku

Maipiku filed an application if you want to view it and become the new Nasan and Maipiku

As is this one (post #305412).

I think Gekka's using a MyPick function, which is similar to a "Show Only to My Friends" function in some other sites, such as YouTube. That means that to view the pic which is set to MyPick, you have to be one of his "friends" first. That's how I interpret what you had described above.

So artists could be posting new stuff without anyone even realizing it except their MyPicks or whatever?

This sucks.

Is anyone Pixiv friends with any of these artists? I'm curious to see how the image URLs are structured for MyPick posts. I tried to download http://img03.pixiv.net/img/milkp/1511298.jpg directly* but it returns a 404 now, so it looks like the URLs for MyPick posts are not the same as for regular posts. If the new URLs follow a predictable pattern then it should be possible to get around this MyPick crap and download the images directly.

[*] You'll need to spoof the HTTP Referer to get around Pixiv's anti-hotlinking protection to do this, otherwise you'll just get a 403 Forbidden error.

Oddly, the five MyPicks posts I've found since I started counting (post #282342, post #281762, post #281730, post #279612, post #278633) were tagged bad id months ago.

For the first type of error, 25 out of 30 were already bad id.

Not sure if you've figured this out already but I might as well post anyways. Sorry for the necrobump.

It seems like the direct links to an image under MyPick/MyPixiv has a set of random numbers and letters generated and added to the link.

For example:
http://img13.pixiv.net/img/-/14888243_02b50826d0.png
http://img13.pixiv.net/img/-/14888386_bcf3e09313.png

And so on. Thumbnails (_s and _m) will have the same numbers and letters applied (http://img13.pixiv.net/img/-/14888386_bcf3e09313_m.png, etc.)

Seems to me like it'll be pretty much impossible to get around this without being added into the artist's MyPick.

What about this from post #724952:

公開制限エラーです。

Google Translate:
Error limit is published.

公開 こうかい open to the public; exhibit
制限 せいげん restriction; restraint; limitation; limit

Is there a pixiv feature for limiting the number of public viewings for a picture?

Don't always rely on google translate, i suggest if you're using firefox, to install the addon rikaichan, so even though you don't read japanese, you can have the translation of a few words, then correlates with google's translation if possible.

公開制限エラーです。

This basically means that the work is not opened to the public, and thus created an error.

I wonder what the difference is between that and "該当作品の公開レベルにより閲覧できません。" (above), then.

It seems to be the same kind of error, changing the pixiv mode to medium returns the "Can not be viewed by the appropriate exposure level of the work." error.
