::Hmm, if sleepers are difficult to detect on highly dynamic IPs, then perhaps that's why  missed the AnarchoGhost account if AnarchoGhost is Pass a Method? I know that you did good with the case, and I don't mean to imply that you didn't; it's just that I'd feel better about this particular case closing with Pass a Method as a WP:Sockpuppet if the technical data connected him in some way. Do you mind me asking for a second opinion on this matter? For example, by pinging  via WP:Echo again or ? I know that more than one WP:CheckUser checking a sockpuppet matter can sometimes help spot something that may have been missed. Also, is it best that the Pass a Method account stay unblocked? How many more times of him using an alternate account in an appropriate way would it take for that account to be blocked indefinitely? Either way, I do thank you for your help on this case. I don't mean to be a pest.
