Talk about previous Housemates on Big Brother?

On BBLB one of the guests said "I know we're not allowed to talk about previous Housemates but..." so why aren't they allowed? Does anyone know?

No idea but Makosi was talking about Jason's leopard print thong and constant preening before.

When HM's go into BB they sign a contract for the series they appear in only. The same rules of privacy apply to them in subsequent BB's as any other person. BB has also said in the past that each series is unique and shouldn't be mixed with references to past BB's.

It's to protect their privacy, just like they're not allowed to talk about anyone else without their consent.

I think its to avoid showing each series in a bad light.

If they were sat around all day moaning about how last years show was better or the house was nicer etc... it would piss viewers off.

Yeah, that's what I thought...but I wasn't sure

Yes, BBLB you said. Not BB.....

I noticed when they compared Kemal with Marco.... Dermot moved the convo on to something else very swiftly.
