The FB rules for boosts do not affect non-boosted posts on either pages or regular accounts. But the motivation behind them is troubling. It seems to reinforce a belief that self-published issue-oriented or "political" content (provocateurship) needs to be regulated by showing the ability to attract diverse support and not just one's own accumulated savings (and ironically that's because self-publishing doesn't cost much.)
This FB practice would seem to comport with a theory, explored Sunday Oct. 7 on the "Issues" blog, that a "political" or issues oriented" page is really a kind of non-connected PAC.
I will not have a setup to sell items in large quantities myself from a website until the novel ("Angel's Brother") is ready for publication some time in mid 2019.
