I haven't heard from RKKatic, but it looks like he edited some of this posts before he deleted his account.

/u/Emperor_Cartagia , who used Reddit exclusively through RIF is Fun, with the death of third party apps, I decided to remove all my content from Reddit. 9 years of comments and posts, gone because of idiotic administration.

If you didn't know, the entirety of both books were written on his phone, with thumbs. So as a phone power user, that pretty much ended his ability to use Reddit. However, with no fallback location or effort to move this community elsewhere, I don't know what that means for The Phenomenon.

The other mods haven't responded yet, and I don't have access to sticky threads.

Both books have been preserved on GitHub here and here. The Amazon listing is still available as well.
