Hi Aditya, This is a good question and one where in the end the person operating the transmitter is responsible for ensuring that they operate legally. Many questions to the mailing list are either explicitly or possibly related to wireless communications systems and GNU Radio gets used frequently for research and work on testing and improving the security of those systems. It is impossible for people answering questions to know for sure that the answers won't be used for illegal acts so largely we must hope and trust that the vast majority of users are doing so legally.
When it is questionable, like this question, I personally try to ask about the application and precautions made to keep the system legal. I'm not capable of knowing all the laws and requirements of all countries or responsible for doing so, but if someone starts talking about RF shield enclosures and/or can link to a company or group with a plausible reason for doing wireless work involving testing jamming or running their own cellular basestation for instance then I feel better answering questions. GNU Radio and SDRs are tools and it is worth everyone being aware that it is likely used by a very small number of people for illegal acts. People responding to questions do so on their own best judgement and collectively as a community I feel confident that we find a good balance.
