Any shill who has the balls to post pthc on THIS board of all places is probably posting from a jurisdiction where they have no fear of arrest. I think the CP shills are likely foreign shills. Possible MOS or CCP. Some foreign jurisdiction. A simple VPN would not be enough coverage.
Which means loli and goreposters may, in fact, be posting from within the United States. They don't have the balls to post illegal content for a reason. Just /b/-tier shock content. I noticed an uptick in loli floods concurrent with ANTIFA posters raiding us. Drawn loli floods may well be the doing of American shills.
Anyway, those are my thoughts on who may be behind the attacks.
