If the server is in a jurisdiction where linking to drug websites is illegal, then it may be a good idea I would hate for the administration of this site to get in trouble over some bogus law. In the USA, linking to drug vendors is a crime under the Ryan Haight act since about two years ago. If it isn't illegal where the forum is hosted, then no absolutely not. I say link to it even if it is illegal because fuck the law, but if the server is in USA I would move it some other place maybe Netherlands where there is no such law and then who gives a flying fuck what the government wants. An even better idea would be to make a bitcoin hidden service.
