I think 4chan may be onto something here. All these "aquariums" on Google Maps which follow the same name formula and same outward characteristics. The pastebin summary and 4chan threads can explain it better than I can cuz lack of sleep.
Here's some links I saved:

Saw this on p.w also in the last couple of days:
