@Sir
I think that Anonymous brings that reputation upon themselves and no one else.
Like the latest (Dutch) news; they are now threatening to launch an all out attack on several internet providers because they block the Piratebay. You can read the (Dutch) article here (link to "telegraaf.nl", a Dutch news website).
Apparently they don't (or refuse to) realize that most of those providers (XS4All and UPC to name two) have actually challenged the blockade in court several times, which has cost them plenty of money. They also seem to ignore the fact that these providers simply have no choice because they are being forced into this.
And here we are now; the providers are going to take the heat from these terrorists, thus most likely effectively hindering many end-users to gain access to the Internet tomorrow.
Does that sound like a sane protest or freedom fight to you? To me its plain out cyber terrorism and vandalism, nothing more and nothing else. The worst (and IMVHO retarded) part being that they actually plan to attack providers who actively protested and fought these rulings, some of them still are btw.
As such; they do it to themselves. Time and time again.
