If you are that worried about spam, set up an account specifically for registration and account information retrieval, and don’t put your personal account online. If you pirated the software and are afraid to enter the SN you got from Surfer’s Serials, that’s what you get for not buying software. You shouldn’t expect a company to smile and give you a thumbs up when you steal their product. The whole process is simple and userfriendly for anyone who owns a legitimate copy of the software.
