Please provide evidence in a list preferably, per member and his altaccount.
Open secrets don't have listed evidence.
There are however lists on this forum with double accounts. I think you can find it under the 'Reputation' section. I doubt that the high members are featuring the list as they are probably cunning enough to hide their alts. There are however threads to be found about moderators giving out negative trust for nothing and even for things they themselves provenly engage in.
It is not against rules to have alt account or to join different signature campaigns/giveaways/bounty campaigns with alts, however if you join the same campaign with alt accounts = cheating = negative rating.
My friend has multiple accounts of bitcoin, and those accounts really help him. He don't get banned. However, to me, we must be careful having multiple accounts of bitcoin, otherwise we will be banned by the moderator.
You are wrong. You will be banned for breaking rules, no one will ban you just because you have another account or two.
