The two active maintainers seem to be: Lasse Collin <lasse.collin@tukaani.org> and Jia Tan <jiat0218@gmail.com>

Searching DDG for "jiat0218" I came across a blog post which I found weird. Seems to be dated: 2006-05-03

Blog post: "Kuso拍賣．有靈氣的筷子 - 闕小豪" <https://char.tw/blog/post/24397301>

The contents of the page when translated seems to be about jiat0218 auctioning a pair of spiritual chopsticks as a prank.

The blog entry is basically a QA between jiat0218 and various other people about these chopsticks.

If Jia Tan does turn out to be a compromised maintainer working for a state actor then some of the content on the blog page can be viewed in a more sinister way (i.e. spycraft / hacks for sale etc.).

Example question 38:

    Question 38
    accounta066 (3): Are these chopsticks really that good? I kind of want to buy
    them! But I recently sent money for online shopping but didn’t receive anything.
    It’s very risky; currently jiat0218 you don’t have any reviews, you can
    interview me. Do you want to hand it over?! … A sincere buyer will keep it.
    
    Reply to
    jiat0218 (4): First of all, I would like to express my condolences to you for
    your unfortunate experience! What can I say about this kind of thing...My little
    sister has always been trustworthy. What’s more, this is a pair of spiritual 
    chopsticks, so I hope to have a good one. It’s the beginning! As you can see,
    my little sister is very careful and takes her time when answering your
    questions. Except for the two messages that were accidentally deleted by her,
    she always answers your questions. If this still doesn’t reassure you, then I
    can only say that I still have room to work hard. You are still welcome
    to bid... ^_^

Note however, it could all just be what it purports to be which is a prank auction of spiritual chopsticks.
