Is ebm.cheetahmail.com Safe?

CheetahMail is a bulk mailer serving Internet Marketing clients, which typically means that the quality, frequency, and respect for your privacy (whether or not you opted-in to receive email) mainly depend on the legitimacy of the IM client. However, CheetahMail is owned by Experian who, as a typical credit-reporting agency, entitles itself to collect as much of your sensitive personal information as possible without first offering you any opportunity to permit or deny such collection. I am not thrilled by the proximity of sensitive personal information and often dubious IM clients. When loaded without a complex URL including subdirectories and parameters, this subdomain displays only a cryptic text string on a blank page; otherwise, it redirects without warning to various operations, including unsubscribe requests, at IM client sites which may or may not be safe.
