Sorry, I only skimmed through your post. To add to my previous answer, MMs (Market Makers) don't usually ever "disappear"-- they tend to just lift their orders up or down to something unlikely to clear in a day, like .0071, or $.0001, depending on which side of the L2 we're talking about.
As for the few thousand bucks at .001-- possibly chartists that ignored or didn't have L2 and mislabeled .001 as a "pivot" or "support". Hope they didn't go all-in. It's starting to look like it's going to stay below .001 for an extended period of time.
