There would still exist a sensible credible and valuable warning for people that directly and clearly look to be attempting or setting up a scam.
I would be in complete agreement with this, but I don't think this is what TECSHARE is proposing. Without putting words in his mouth, he seems to be arguing for not tagging anyone until after a scam is committed:
The only places with preemptive policing are totalitarian governments where individuals have little to no freedoms. This isn't something we should be emulating no matter how much you jerk yourself off about how great you are and convince yourself you are stopping so many scams. You aren't stopping shit and this behavior is self serving.
