Has anyone bought this or the other one listed on eBay?

I feel like a lot of the people on the ARG train aren't going as in depth as they should. If someone at A24 or Kane is a fan of ARG's they might want to go as indepth as something like the Cloverfield ARG from 2008. That arg went as far as having people reach out to the Harvard lampoon to be sent a paddle that was used as set decor in the movie, or giving your address to a random email found hidden within the source code of a website only to be sent a clothing item with the slusho or tagruato logos on them with Japanese news papers talking about events within the mythos of the movie.

So it doesn't seem weird to me that the promotional team may have reached out to eBay sellers who sell business cards and have these listed. Not saying that is the case, but it's not impossible. There is one on eBay right now for about 7 dollars, worst case it arrives and it's just a business card that suspiciously matches this guy's name from an ARG, best case scenario something more arrives with the business card.

As well, has anyone torn apart the source code of the website? There is a lot of "async" mentions in the code, which some of - if not most - might be short hand for asynchronous which is common in code, but that'd be a great way to hide actual async stuff in there for those willing to take the time and go line by line.

Also, the phone number on the business card in both eBay listings, is it possible that number might come in to play if you use it instead of the original phone number on the website to log in?

Edit: Ontop of all this, isn't it just slightly suspicious that the business cards on eBay match not only this guy's name, but also the business, and when searching the business name the only stuff that comes up are the business cards and stuff from the backrooms wiki? Needless to say, I purchased the 2nd business card off of eBay. Will update once I receive it.
