D. Well, I'd like to make this into an API if I live long enough to do so. Quantity of workload is just too huge for one person. If I succeed, client side will go open source. I see why not.

F. Since I use a NoSQL scheme and have valid injection failsafes,it wasn't it. I suspect a primitive curl script that rendered my server useless by overloading my daily quota of resources. That will not happen again.

Sure sooner or later someone would point this problem out. You have my utmost gratitude for doing it right now at an early stage.
