the guy who made tsuki was a mentally ill redditor with an abusive mother who said he would kill himself by July 1st and spammed his alternate reality on 4chan and various other sites, until he made systemspace to try and encourage other fucks into killing themselves. I never checked the site around July due to a lack of interest to role-playing
as an occasional browser of pre-delet lainchan, the new admin never changed the admin password, and the old admin (whow as a massive fag btw) just deleted it for lols
I think it split into two sites, lainchan.org maintained by the staff team by the time of the accident and lainchan.jp (now arisuchan.jp or whatever) which was just a split website by some random community memebers, it was literally the same as lainchan.org as a site design-wise for a long time
I never liked lainchan as a site because it just shat on the entire SEL legacy. There are various other reasons to dislike them, such as their "MLGhax0rgz freedom fighters" thing and the horrendous staff team, the "cyberpunk" board without a /cyb/, the whole cyberpunk movement in general (which was quickly overtaken by 80s nostalgia and vaporwave aesthetics)
The community itself aside from the designated shitting spots was nice.
