Does it currently exist?
Do something significantly illegal enough online most anywhere and you will be caught. Other than very specialized internet usages that are outside the purview of the common individual, the only question currently is if the government can justify going after you, not if they can go after you. Right now if you point out corruption against a local government they likely won't go after you due to lack of resources, not technical limitations. Point out major corruption at a high enough government scale and you will be caught (especially given that one will have to go outside of legal channels to do so).
