The one important fact in the entire article is that the NASDAQ applied (with much media coverage) to tighten their listing standards and exclude many of these low-priced foreign IPO's, yet they keep accepting and listing them. An obvious cash grab by NASDAQ sure, but they also may feel the need to pad their listing numbers for publicity sake.
It seems to me that this group behind these recent listings and social media pump and dumps are intentionally trying to beat the deadline.
And yes, all 5 of the recently suspended stocks are connected. No doubt.
