"Dear users, in the light of recent events in France we have decided to remove our Weapons section and we are going to disallow weapons on our Market completely. Reason is it is not very secure for us to sell weapons here anymore. Thank you for your understanding. "
I have to commend them for making such a move, I know people will be strongly disagreeing whilst others strongly agree - weapon access is generally a controversial discussion. Ultimately, DNMs are probably not a big source of weapons involved in these events, but making certain items harder to obtain can discourage a few non-dedicated people who are only toying with an idea.
I love guns but it is a good idea not to have them on these markets. Not because people shouldn't have them, but because with all of the heat on the DNM's right now guns will just draw more negative attention. I know in the U.S the would make commercials talking about DNM's being the route to terrorism. The worst part is the people will believe it.
