While growing a group to 1 million members or more is possible, there are very few groups of that size on Facebook. The ones who have reached that level were aided by widespread media coverage (ant colony group, The Blackout Coalition), are set around a topic that has a large following (FIFA, manga, Netflix, humor, maths) or is something that people are passionate about and spend a significant part of their day in (instant pot, keto diet), were really on point with a trend (Family lockdown tips, View from my window).
