Lambdaplusjs

Lamdaplusjs, (Lambda or L+js more colloquially) is an imageboard accessed primarily through Tor, but is accessible on I2P and Yggdrasil as well. It is notable due to its involvement with Nanochan and its related sites, moderating by moving posts rather than removing them, userboard creation, and persisting all posts (except CP images). The site has been around since November 2021.

Rules

The rules are vague at best, but as of April 2023, the following is listed for moderators on moving posts:

• Child porn and CP links can redacted and moved to /spam/ with the "CP"
• Advertising and blatant flooding can be moved to /spam/.
• Long-term, excessive patterns of silly posts that aren't responsive to the conversation and clutter threads / boards can be moved to /free/.
• Double posts or posts remade with corrections can be moved to /test/.

Furthermore, there is content that is "not tolerated" or "unwelcome". Still leaving ambiguity:

• Using lambdaplusjs to commit crimes or post personal information is not permitted.
• Child porn and links to child porn are not tolerated and will be deleted.*
• Drawings and other art not involving real children are not considered child porn.
• Photographs of sex acts between humans and animals are not welcome.
• Threads should not be made solely to dump erotic images of real people.
• Multiple active threads on nanochan mod drama or race politics outside /free/, or derails of unrelated threads to these topics, may be consolidated into one containment thread each or moved to /free/.
• Posts and threads may be moved where the admin feels appropriate.
• Boards not deemed a good fit for the site will have their contents moved.

URLs, Source code, and database

Lambdaplusjs can be accessed on the following URLs:

Tor1

http://lambdaplusjs35padjaiz4jw2fugdoeutse262phqr72uf634s2wdbqd.onion/

Tor2

http://z5lcip4dafatwwa6hvyibizpzwycvwp67cjga3hzjhxhwvuyaqavxnid.onion/

I2P

http://l7jqnz3yfe2wtwietafoieadmgqbu7dcmzmey63ktbjtxal3he4a.b32.i2p/

Yggdrasil

http://[200:e111:a7c7:6fee:8a1b:90a7:2b17:79ec/]

The source code is written in Lua and can be accessed at /Source/ on either of these. It includes a git repository, so it can be cloned. The data can be accessed at /Data/ as well, including posting data, thread data, moderation data, etc. Images and their thumbnails are kept at /File/. The only thing kept private is the captcha solutions and moderator passwords. The installation is currently broken because you are not presented with an admin/password login during install so you cannot access the control panel.

Posting and formatting

Posting does not require JS, instead relies on POST requests. Formatting is limited in nature, it supports the following:

• Links to posts and threads, only needed to be prefixed with the letter P.
• bold text
• spoilered text
• simple quoting
• a subset of LaTeX

Community & criticism

As of April 2023, the site is still moderately active getting above 100 PPD. There are 7 moderators, but barely 2 are active.

Many people accuse its admin (lambda admin, ladmin, or soymin colloquially) of shilling his site on other Nanochan related sites and later turning to deny that happening in the first place.

The admin formally banned the use of wojaks and is seen acting on excessive soyjak posting, but the rule is not enforced strictly.

The site is frequently spammed with many things, but the most consistent and largest volume spammer is known as "historicalfag" due to their use of XIX. century or early XX. century images and topics.

The site shares much of its userbase from former members of the now defunct Nanochan so the board culture was inherited mostly from there. But it did not stop the site from developing some slang and history on its own.

Spinoffs

All of these lack activity some way or another.

• nyaiwdyri5wy2hqtmmquq2zlpl66jc5oc5die44j6kjqkaia3ozzneyd.onion OG - Launched on the 6th of April 2023, announced on the 19th. It hosts the same software as Lambdaplusjs so it can be presumed that it is hosted by the same person that asked on instructions on hosting it in a thread. Also the site was filled with historicalfag's newspapers and mod accounts accordingly named so it could also be historicalfag running the site.
• hgiztpdbheg4cnievh3bb7bh3kcqlomk56y4sbocr54x3txfx3rpmpyd.onion - Currently (April 2023) it just displays "Lambdaplusjs" with one of historicalfags avatars and links to various popular boards of [Lambdaplusjs] along with more "hidden" ones. It was posted first about on the 13th of April, 2023.
