With the advancement of technology there are 
many problems also. similar is the case with mobile phones. now adays matric 
papers are going on and i have seen many boys taking photos of girls with their 
mobiles. later they mis use it on the net. also sims that are being used by 
these boys are not registered so there is no way one can apprehend these 
culprits.mobile companies should make a policy that any sim without ID card 
should not be issued.There is added responsibility on everyone of us to address 
these problems.
