I've done it once. Got .00001 instead of .0001, selling at 'Market'. I'm sure very very few tried that EXCEPT Insiders, P.I.R. groups that have been paid in shares (anything's better than zero), etc... JMO, of course.
The parallel between ARIO and NXHD is about complete. ARIO did not average .0001, yesterday, (more like .00008).
g.p.
Brokers will usually not let you trade at market for .0001 stocks without verification.
