I can not agree that it will harm though.
For instance -we have proven scam I am not gona cal names. Then suddenly new thread pops up with newbie account posting you know I saw this and that
What harm can cause a list which CLEARLY SHOWS that proven scammer and newbie are using same clas c without revealing their ip adresss
Second newbie comes and says hey you know I both this from here and it works great. Another one shortly comes and says yeah same here and so on
Just a list to be published somwhere regulary that is what I am after
