FrumWithQuestions notes that AishIsrael.com (and, I see, .org) leads to the Chabad.org homepage. DixieYid, in a comment on FWQ's post, notes that this is most likely illegal and believes Aish HaTorah would prevail in court. Both aishisrael.com and .org are registered by Domains By Proxy, which is a company that, in effect, creates private domain registrations that protect the names of the actual domain holder(s).
