I also wonder how guests are handled.  I would assume the rule for this are strict and would not be surprised if there is some notification posted somewhere. I would also assume the housemates are required to tell guests about the cameras are face immediate eviction.  Also the cameras are visible not hidden.  

cameras are visible yes check out this link no wonder tenants are sometimes scared to show their body

another thought ..if things dont change..they will stay the same

Highlight of my flick through tonight is M&S's cat yawning -  must get here earlier

where are the male masturbation vid?

There are several of the women who fancy themselves artists. Are they any good?

Could be many reasons why they occasionally sleep on couch. 

TV and lights being left on just pure laziness. Obviously never been taught, or had to pay bills. 

Sleep when they want. Not like many then and now have much else to do. Being on devices most of the day. Never know when sleep might takeover. 🤣

No theories and couldn't care less.
