Dangerous? Probably.

Bad? I mean, at some point, it becomes a risk assessment. Organizing at the risk of physical discovery might still be worth it, depending on your goals and what you're willing to sacrifice. The benefit of these networks is that you don't need tons of funds or construction ability to set them up. Whether you are an activist, a hobbyist, or a political dissident, you don't need a government or business to do it for you.

It's not really my place to determine what someone's best strategy is, as strategic factors are likely always changing.
