I think the producers just have a quick glance over them to make sure they are not offensive, like no curse words or anything offensive on them, but i thinkthe signs are genuine.

I've noticed in BBUSA on the finales though, all of the signs are definitely fake, you can tell because all of them are written in the same style and font, and they just look too professional and neat.

I've noticed on BB Australia aswell they look fake sometimes.

But the BBUK ones always seem real.
