Hi, Jim, I just read the draft and feels not sure about some point: In the last paragraph of section 1, you said: " In order to permit useful reputation accrual, the value of the reputation tag will typically need to be stable over a relatively long period of time. The use of a tag which is independent of other identifiers (such as email address) supports this need by providing continuity, even when other identifiers change. " After reading this paragraphy, I found I was not sure about to whom the tage belong. You said it's independent of email address. From the first example case in section 1, it looks like each tag belongs to a user. But a user might have both premium and free accounts which have different potential of abuse, as you mentiond in the section example case. The purpose of such a tag is to provide a finer level of granularity than a domain, but it's not clear which level it is.
