It’s not just about views though unless you’re a third party studio who possibly get paid per view (I don’t know how that works).
For SLR’s own stuff, it should be about attracting new subscribers. Diversifying a little may result in some scenes with smaller viewing numbers but may actually get new subscribers who want to see that stuff in VR.
For example, let’s say SLRO started doing 3 interracial scenes per month. Those scenes may get a bunch of negative comments, may get 1k likes instead of 5k likes but, of those 1k likes, maybe 200 are new subscribers who signed up for IR content whereas the 5k likes on the standard scene are just the same people who are here all the time and probably have lifetime/annual subscriptions already.
Doing the odd different scene isn’t going to cause anyone to cancel as they’ll still be getting what they want 90% of the time. It may help grow the membership though if you add some niches that other people may be looking for. Just making the same scenes over and over to keep the existing members happy won’t grow the site and those existing members will eventually get bored with the same thing and leave anyway. People who watch a lot of porn generally get bored with the same porn after a while and move into new fetishes to keep things interesting.
