Some reporter(s?) in Germany found that all the forums for CSA actually host their material in the clearnet, i.e. on Google Drive, Dropbox, etc. (since TOR speeds are shit and those people don’t watch SD videos anymore).
The police could have demanded data from the uploading accounts and that the material was taken offline. They refused to do so, in order to “catch more criminals” or something like that.
So, their “think of the children” is exactly as in the spirit of Helen Lovejoy as it seems.

Not anymore, right? Or does it still need your number for signing up?
