As a general rule of thumb, if I've seen a URL shared on 4chan, I assume it's either a honeypot or a service people will judge me for associating with. I also avoid clicking such a URL because it's the kind of place I'd expect to find a zero day WebKit exploit.
With the caveat that you should fully expect catbox.moe to be added to your organization's blacklist if it hasn't been already. It's kind of the premier service for sharing content that falls into the "legally grey but no big service will ever let you keep it on their site" content like mass shooting videos, etc. Just don't get used to relying on it at work is all I'm saying.
