domainoid, my stats don't show that. Most domain thefts occur at GoDaddy, and definitely Moniker. In any case, the most common method used is email phishing, that primarily plagues GoDaddy due to its popularity.
eNom is not known to be an unsafe registrar, however, they are not taking the approach most domain owners would like to see, when it comes down to actively pursuing the return of stolen domains.
