Looks like Hololive Bunny Garden streams are starting to get privated. So far, Miko's, Ollie's, Anya/Kronii's, Ao's, Watame's, Koyori's, Hajime's, Okayu's, Chloe's, Polka's, Octavio and Nerissa's have been. If you have any that you particularly liked, you should make sure to grab a download of it while you can.
Bae's, IRyS', Pekora's, Aqua's, and Axel's are still up of all the ones I checked.
