This could have an impact but what about groups and pages? To be honest their ROI on ads is crap anyways lately. I think we will be looking at more targeted marketing of STISH to people that get it. Maybe several daily major blasts on Steemit with large upvotes to spread the message to minnows. We are selling pre-ico so far and doing good. I might fire the SteemThat.com bot back up for marketing purposes temporarily soon too.
Overall Facebook is stupid.
