Onerep is a privacy monitoring service/ privacy provider that Mozilla partnered with for their Mozilla Monitor service.

Yesterday, Brian Krebs (a cybersecurity journalist) dug into Onerep and found that the CEO is a shady Belarussian. Dimitri Shelest, CEO, of Onerep owns multiple "people searching" websites. Shelest has also been linked to aggressive spam and affiliate marketing emails.

Onerep's reputation is shady due to their CEO's multiple conflicts of interest. At worst, Onerep is sucking your personal information. At best, you're paying for a service that doesn't do anything. Either way, I would not trust Mozilla Monitor service .
