Never mind the domains, they are undoubtedly the same ones that sendsafe has
infected. Look at some of the companies. Many commonalities; in choice of
stock promoter, locations of principals (Penticton BC is one that comes up a
lot), most are so thinly held it's probably just the owner and close
relatives, and many are successors to previously spammed entities, or are
connected via shared directors with CWTC.

This isn't only pump and dump spam, a lot of it is create a company, "issue"
(declare) shares, publicise some "intent", and price targets,  pump, and
run.

A number of these companies report no revenues for several years. (never
mind profits)

There are even a surprising number of dotcoms with absolutely no net
presence I can find (except for spam complaints).

It's very smelly.
