I was apart of a finance student group in college. We used MailChimp to tell members about meetings. I remember our account got automatically flagged and locked once because newsletter contents included details about a forthcoming stock pitch presentation, and that apparently was close enough to a ToS violation that MailChimp froze us.
The funny thing was that our student group was allowed to directly invest a trivially small portion of the university's endowment in the stock market, so we were not soliciting others to buy stocks - the presentation was a confidential, internal one about how to invest our fund's own money.
