They say memory card unlocker itself is not illegal but it helps in promoting by using it illegal activity, well persons who interpret policies of trust and safety are like brainless adjudicators, they cannot explain their policies but well they do bullying.
But what illegal activity under any ipc or any indian law could usage of memory card unlocker do, then they should ban even selling staplers as one can kill some person with it, and what about swords or knives ??? Or ban selling computers they could help in making viruses, which is illegal, ban laptops , and mobile phones well they can be used in lot of illegal activities like extortion calls, eve teasing etc, and tresspass of privacy by their mobile phone cameras, why do`t they ban this also.
Stupid answer as memory card unlocker in directly helps in illegal activity.
