By the way, isn't "promotion" part of what Investor Relations should be doing?  I think so.

However, when a company is hired covertly but essentially to spam public message boards, they are not constrained by the same rules as employees of public companies - and I am not saying I know that's what's happening here.

And, I could undoubtedly be wrong in these observations about the "wonder"ing of the engagement you mention.  It could also be for hosting a shareholders meeting at Starr Pass Resort in Tucson with a field trip to Hay Mountain.
