Because anyone has the right to scan in whatever range or puzzle they want, without the opinion of others. Some members of this forum are under the impression that they have discovered patterns, that they have "clues" about private keys, with the claim that they have accomplished great mathematical achievements. The truth is, the main factors that can lead to success in this puzzle are processing power, how to choose the ranges and a bit of luck. The rest is bullshit and useless chatter.
