I don't want to defend anyone, but if money is lying on the road and no one takes it, simply because it's someone else's, do you believe this is possible and no one will use it?
The forum allows alternative accounts. But these alternative accounts are not allowed to cheat. What does the forum do to prevent cheating? Nothing. Only people who catch cheaters sometimes prevent them from breaking these rules.
If it were impossible to register hundreds of alternative accounts, there would be no temptation to milk the forum. At least not everyone can change their IP, device, MAC address, and everything that is not allowed for cheating on other sites.
I don't believe that people will be honest just because the word "forbidden" is written somewhere. They will take advantage of the opportunity where there are loopholes. Poverty and greed give birth to the desire to break the rules; those who are not in great need will follow the rules, but there will be very few of them. However, since the forum does not prohibit anything globally, the mistakes of those who are inattentive to their alternatives and allow detection of your own judged fairly.
Convincing and valid arguments within the scope of signature earnings/bounties.
Though the very existence of this wonderful place is not centered around
signature earnings/bounties, I do not think the forum should compromise on its core vision (which you know much better than me) just to prevent some cheaters/potential cheaters.
Personally, I think it is impossible for someone to grow here without a serious commitment to learning, and if someone compromises he will be caught sooner or later. I think you were the one who gave the drug addict analogy, 'It will never be enough for them' in one of my threads.
