NOSPAM is a service to report spam messages and unknown numbers. According to the telecom laws and regulation in IRAN, using the telecommunication infrastructure to send unwanted messages forbidden without people's consent. However, since there are so many abusers and the law enforcement is happening slowly and privately, people may not have access to an open database to determine the calls and messages they are receiving are legitimate or not.
NOSPAM provide the infrastructure for the people to report the spam messages and unknown callers so the others can use this information to prevent unwanted dilemma.
Highly recommended for those who value their privacy.
