>>16965646simple and honest answer
1. because we were focusing on stream ccv since the start
2. premiere numbere were unreliable for a long time
3. long term, reliable numbers listing sites like HoloStats and niji-mado don't record them.
So even if something like vrabi appears every now and then that records them, the numbers can't be verified in other places and vrabi only records 1 month's worth of data.
Also, falseflaggers like to use Premieres too much for trolling. So there's a lot of bad blood against them.
