I think there's more too it besides the Bandwidth. I have been saying for the last 2 Years this day was going to come where RLC started making most of their Site Premium and just leave the Free Viewing of the Garbage Apartments where hardly No Activity exists. Plus they are likely striking a way too Suppress Posters from Posting Picture and Video Content to cut down the use of Copyright Infringement
Leora & Paul's Apartment has been changed to All Premium as well. There's likely a few more that's going to change like Kitty & Smith, Olivia & Nick, Ulyana & Marat and Dasha, Sasha, Masha.
It's coming to a Point RLC will make the Whole Site Premium. " You'll Have too Pay to Play "
