Attention: mobile operators

Pradyut Kumar Saha, Kalabagan, Dhaka
Different mobile operators are advertising call blocking option of their service. The technology is good, but I object to the idea of advertising it. The advertisements are presented in a way as if disturbing calls are a matter of fun. Such calls are a social crime and civic nuisance. Perhaps all mobile phones are now registered and it is possible to find out the caller. So there should be this warning message to disturbing callers. Sometimes disturbing callers do it in groups (!). How many callers' connection one can block or how effective the option is? I request the mobile operators and telecom authorities to think about the matter.
