As Edmund Burke is paraphrased as saying, "The only thing necessary for the triumph of evil is for good men to do nothing."
This is good men and women doing a great thing. For those that say that the bad people will find another way, I say, "good." They need to be shamed into a deeper and deeper hole, and hopefully, those that are caught will provide those that are inching towards this depravity an exit to leave this activity.
While I whole heartedly applaud any and all efforts to do this, it is not likely to succeed 100%. As we all know, once anything is on the internet, it is forever. Hopefully this effort can and will slow down new instances of this filth, and maybe help to eliminate those existing instances that are wide open and not well guarded by the people who host such garbage.
