I disagree with you. If someone can't pick games on their own, they shouldn't be gambling. Blindly following someone without doing any work should leave you poor & rightfully so. Winning takes work, & should be treated as such.
Of course to leech off someone's picks is not really a nice thing. But if you know the picks of a successful capper and bet them how can you fail to be successful yourself, assuming you manage to get the same lines? What do you think is better money-wise, putting a lot of work into capping and still barely hit 50% because you don't have the talent to find true value, or hitting 56% because you blindly follow all picks of a proven capper? The real problem appears to be to find someone who is really a long-term successful capper.
But actually I wasn't talking about the ethical or practical side of tailing. My point was only that if you tail, you should do it blindly and not question the picks of the capper you follow because if you know that you are not able to cap successfully yourself it is likely that whatever appears to you to be wrong with the capper's reasoning will just be wrong judgement on your part.
