Does Anonymous's association net help or hurt the anti-ACTA position? And historically, did it help or hurt anti-SOPA/PIPA?
I generally took what they do as being emotionally gratifying but having zero real impact, but by giving the un-informed but not necessarily malicious (and potentially the intentionally malevolent spinsters) an easy way to justify onerous regulation, I think they may be hurting the causes they ostensibly back in the long-run.
