For starters, COTSE isn't a remailer but more of a front end for the remailers. COTSE doesn't claim to be a remailer, not do they claim to be completely anonymous. COTSE provides a privacy shield, nothing more. Logs are rolled regularly from what I understand and while the logs CAN be made available to law enforcement upon presentation of a subpeona which, IMO is a whole lot better than a true anonymizer which opens you up to illegal acitivites and other abuse. Personally I wouldn't run a true anonymous service just for that reason.
