This page gives a short overview of safe.moe's history. (tl;dr your files are gone)
The cuntflaps era
A few years ago, a person named Alucard created a Pomf clone (a file hosting site similar to the now defunct pomf.se) called cuntflaps.me. It used a fork of the original Pomf software. Later, a secondary domain, fluntcaps.me, was added to make it a little more safe for work.
In his words:
Back in 2013-ish on a drunken evening with some friends I discovered earlier that I can get a free .me domain via nc.me. The next day I woke up to a raging hangover, and a new domain called cuntflaps.me what happens next is the creation of another pomf clone which has grown far more bigger then I could ever anticipate. We are at 50 thousand files, and serving 20TB of bandwidth a month, but I hear from countless hesitant users that the name is immature, ...
A new name
While cuntflaps/fluntcaps was pretty successful, the name was still rather immature. In a move to try to fix this, safe.moe was born. It no longer used a fork of the Pomf source code, but was now powered by lolisafe.
How Alucard explained the rebranding:
[If] I want to take this site anymore further I have to ditch the childish and funny name in favor of something more simplistic, and your IT staff won't laugh at and call HR when they go thru your browser history at work, so now safe.moe was born. This was chosen as cuntflaps has always taken a more waifu culture type of direction with the home page and 404 pages, and I think its pretty sugoi tbh fam, so now I have made 301 redirects for old cuntflaps uploads that will goto the new file server a.safe.moe and have migrated everything over for the most part except for the tracker which will have to get figured out somehow. But oh well
The end of yet another Pomf clone
In late July 2018, Alucard's hosting provider suspended and terminated his account. Since Alucard had no backups, all files were lost. In early August, Alucard sold the domain to lesderid of fuwafuwa.moe.
safe.moe's future is currently rather bleak. But, the domain is for sale, so perhaps you can make it into something great.
