This disclosure is directed to techniques and systems to verify an identity of an applicant to enable the applicant to claim accounts, domain names, electronic messaging addresses, and/or other computing resources in a computing environment. The techniques may use a voucher system that relies on approvals (or vouchers) from members that each has an associated reputation score. The members may vouch for an applicant that submits a request to claim a portion of content. The portion of content may have an associated verification requirement, which may include a predetermined number of vouchers from members where the reputation scores of the members reach or exceed a threshold score.
