The Duggar family have become virtual shut-ins following revelations that Josh Duggar had an account with Ashley Madison, a website that exists solely to help people cheat on their spouses. Duggar, in a statement after Gawker uncovered his two paid accounts with the website, said he had a porn addiction.

Citing an unnamed source, Entertainment Tonight reports that Josh Duggar and his wife Anna have holed up in a farm house in the mountains of Arkansas, which he purchased for $55,000. The rest of the family, made famous by their stint as reality show stars on TLC's 19 Kids and Counting, has apparently been on lock-down.

The family has been staying indoors at their Springdale home, even missing church on Sunday, which is unusual, the celebrity gossip site reports. The sermon so happened to address infidelity.

Anna Duggar has been silent but appears to be standing by Josh, though her brother, Daniel Keller, has blasted her husband and offered to come get her and let her stay with him with her four children.

"I told her I would go get her and her children stay w me," Keller wrote in a scathing Facebook post. "She said she’s staying where she’s at. But I won’t stop trying to get that pig out of our family. I tell you who I don’t give a s— about is that pig she calls her husband."

The Duggars had been active campaigners against LGBT rights, with Josh Duggar heading the Family Research Council, an organization vocally opposed to same-sex marriage.

Before the Ashely Madison story broke, In Touch Weekly revealed Josh Duggar had molested five underage girls, many of whom were his own sisters, and the family had covered it up.
