At least 10 members of the nonprofit Bitcoin Foundation have resigned over last week's election of onetime Disney child star and current Bitcoin entrepreneur and financier Brock Pierce as a new director, officials at the group said.

Some of the members cited Pierce's troubled past. That includes allegations in lawsuits from three employees of Pierce's first company, bankrupt web video business Digital Entertainment Network, that he provided drugs and pressured them for sex when they were minors.

Pierce has denied the accusations, which first surfaced in 2000.
