Cicada 3301

Excerpt from the Wikipedia Page:
Cicada 3301 is a name given to an anonymous organization that on three occasions has posted a set of complex puzzles, purportedly to recruit capable cryptanalysts from the public. The first Internet puzzle started on January 5, 2012 and ran for approximately one month. A second round began exactly one year later on January 5, 2013, and a third round is ongoing following confirmation of a fresh clue posted on Twitter on 5 January 2014. The stated intent was to recruit "intelligent individuals" by presenting a series of puzzles which were to be solved, each in order, to find the next. The puzzles focused heavily on data security, cryptography, and steganography.

While it has been called "the most elaborate and mysterious puzzle of the internet age,"much speculation exists as to its purpose. Some claim it is an Alternate Reality Game (ARG), but the fact that no company or individual has taken credit or tried to monetize the puzzles has led some to feel that it is not. Some have speculated that it is a recruitment tool for the NSA, CIA, MI6, or a cyber mercenary group. Others have claimed it is run by a bank working on cryptocurrency.

After reading that, would myself hosting one of these challenges interest anyone here? I hosted one on HF and it didn't get much attention.

Could you send me a message or something with a link to your challenge on hf ?

I attempted the last 2 ones, I'd join this one too.
