A guy claiming to be my friend visited me in the summer and gave me his mobile number I called him at my expense but this man not practically wanting to talk to me anymore used the blacklist feature to block my incoming calls was it not better to speak out saying please do not call me.
A building contractor also applied this same tactics to avoid me I sense a hazard in this practice boys can tease and harass girls and block the girls parentd &relatives numbers thieves can loot homes this blacklist option if used by terrorists can be dangerous I think it should be removed from all mobiles worldwide
