What do I find annoying on facebook?

All those friend requests from people you don't know...

At first I added one or two as friends, then I realized what it was about and now they all go for a fake account report.

They also end up marked as spam..

I am however wondering how a company that makes billions is powerless to setup some kind of proper spam filter and I have a greater understanding in why the process is manual on Steemit. I still look forward the signup to be automated so the community can grow, but fear it will end up like FB with people who want to be your "friend".
