Signups from btinternet.com: real people, repeat trials
btinternet.com is not disposable, so blocking it would turn away genuine customers. The risk is different: the same person signing up again and again to restart a free trial. A +tag (jane+7@btinternet.com) reaches the same inbox as the plain address.
