Apparently spng has its own schedule of releasing its financials, when it deems fit. And we all just have to wait for that, if one has the patience to do so.
We do not know exactly what documents were requested and it is very difficult to speculate. My guess is that they needed to stand behind numbers that were PR'd and defend themselves with documentation regarding numbers posted in prior q's due to the drakeford nightmayor and the accusations made by STI (Michael Popovsky)and Kaja Whitehouse of the Post.
Do not forget that spongetech has a pending lawsuit with STI and are filing some very serious charges against them including Trademark infrinegment, Trademark dilution and defamation. I am not sure if you have read the complaint but it is extremely bullish and SPNG has accused STI of stating to the NY Post that the Sales are "impossible" and knew it would be published. I will give you a link in case you have not looked it over yet.
I suspect that some withheld information may have something to do with a pending lawsuit but even in its absence, we still have a mountain of people wanting to see this company fail and information at this point could only help that effort. This is all in my opinion of course but looking at the bigger picture helps understand the possibililty for temporary non disclosure of certain information.
As to your last question I can only say that if they are scamming thousands of people then the answer is no. They would not file information that would incriminate them they would simply fade off and lose their position as a public company never report again, Don't you think? Personally I would be looking for international airline tickets. We would eventually learn how we got scammed but the prospect of a scam does not ad up anyway. If so it would be very elaborately coordinated.
