[3] Heldal-Lund served on multiple boards for the national secular humanist organization Human-Etisk Forbund.

[7] Heldal-Lund first became interested in the Church of Scientology in 1996 when he read about Magne Berge, an ex-member in Norway, who sued the organization in court and won.

[2][8] Heldal-Lund started gathering information about Scientology and eventually began hosting the materials himself as part of a project he called Operation Clambake.

[18][19][20][16] Most of the information presented by Operation Clambake is critical of the Church of Scientology and its leadership, although dissenters are given prominent space to air their differences.

[15][2][17] However, Mike Rinder, a former executive director of the Office of Special Affairs for the Church of Scientology[22], and Leah Remini, a former Scientologist, put forth another theory in a conversation with Heldal-Lund in their Fair Game Podcast.

[16] Xenu is a central character in Scientology's creation myth[23] which can only be accessed in higher levels of the church.

[24][25] Scientologists are required to sign a confidentiality agreement that contains a clause stating they understand they will be fined each time they speak about the materials with anyone else.

"[15] The church also targeted his ISP, network service providers[15] and filed Digital Millennium Copyright Act (DMCA) takedown notices with both Google and the Wayback Machine to remove links to xenu.net.[17][28].
