I actually use Facebook all the time.
I run a political discussion group with around 33,000 members, a meme/shitposting/friend group with just over 7,000 members, and on top of that, I use Facebook groups for selling sneakers and clothing to other members. There's loads of dedicated groups with up to 150,000 members, all about sneakers and expensive clothes.
Really? Missed the potential for business outside of advertising. Thanks
Some of the biggest groups are The Basement and Yeezy Talk Worldwide. ;-)
Thank you
