>>44643029Chink clippers (hololive moments) were a huge factor on making hololive explode outside Japan. Kinda funny how holofans hate China now.
Good quality control as other mentioned, there have been yabs but they're minimal compared to other corpos like Nijisanji. The girls know they shouldn't collab with males, the whole idol thing appeals to idolfags as well as give a feeling of watching a girls only school as Miko said.
Lastly, when hololive exploded in popularity there weren't a lot of girls so you could watch all of them and settle for an oshi/pick your favorites and be able of watch clips of the rest at the very least. This is very important because humans are brand loyal retards (just check the whole board and the numbertrash thread to see this at its peak) so viewers consider themselves fans of hololive as a whole even if they don't watch all the girls. Whereas doing this with Nijisanji is impossible because there are way too many streamers.
