"We do not have plans to advertise on any future episodes, because there have been certain segments of the show that made us uncomfortable," said a P&G spokesman.
Unilever, a second member of the forum, said it is reviewing its sponsorship. Viacom's CBS declined comment.
Last week the Parents Television Council complained that an episode in which now-expelled housemate Justin Sebik threatened violence against a fellow housemate violated goals of the Family Friendly group and questioned why forum members aired ads in the show. P&G said its decision was unrelated to the group's complaint.
