The problem with the cams on SLR is not the girls, or the app (although the app does need work), it's the lack of customers.. I have seen some super hot girls in SLR cams before and they never stick around, because when you go into their room there are 3 viewers and one guy tipping 5 or 10 tokens at a time, never the 100-2000 token tips that you see constantly on cb and other sites.
At the end of the day, if she's giving the VR viewers the whole show for free because she's dual streaming on another service(s) and getting tips from those, there is literally no reason to stay on SLR and get nothing..
Remember that a decent VR setup is sill a fairly expensive proposition -- If these girls don't get ROI relatively quickly they are better off selling their gear while it's still valuable rather than making a few bucks a day.
SLR needs to help these girls monetize better, either by promoting the cams feature (and vr porn in general) so more viewers come in, or getting them under some kind of contract or royalty where they get a decent amount of regular income, (maybe their shows can be recorded and shown on SLR site etc)
If you can't give the models ROI on their VR equipment within a decent time period, the good ones are never gonna stick around and you might as well shut down the cams and focus on your bread and butter stuff like original content and haptics.
