It's a fair question, and shows that a lot of these sites are like icebergs - they look simple until you delve beneath the surface. How are you detecting human trafficing and reporting it (FOSTA-SESTA)? How are you detecting CSAM and reporting offenders to NCMEC? How are you detecting and removing spam? How are you preventing fraudulent ad clicks? How do you deal with "whale" accounts (very large follower counts) and returning an algorithmic feed for their followers? I interviewed for their deveng team and they were doing things like build-caches because it sped up compiles and increased productivity. Also optimising the Scala compiler (more productivity gains).
