Anything to worry about if you use mixers and not doing anything illegal?
Will any one come knocking on your door if you use mixers and not doing anything illegal?
Will posts like this be banned too after Jan?
Will using mixers be an expensive?
If you know that you are not doing anything illegal and just using mixers for your privacy then why you have to worry though? Nah, I don't think that someone men in black will come knocking at your door just because you used mixers. They are still legal to use per se.
