Nobody molested anybody. The most we saw was last saturday when Michael kissed pointy-nose girl on the arm and she told him to knock it off. She then complained to Eric and Eric kinda played it off like every girl in the house was scared of Michael because he was sexually harrassing them.
Eventually, Eric put Michael up for eviction and Michael got pissed. They played on each other’s nerves for a while until it all came to a head (because Michael made some stupid smartass remark about Eric’s grandparents - in private to Janelle, no less - and Rachel heard it and ran back to squeal to Eric). They almost came to blows, but were separated by the other houseguests and the producers ordered them into separate rooms. Then Kaysar and Ivette started getting heated and the producers made everyone go to a different place in the yard until everyone would cool off.
