Your questions are very stupid ones however I am trying to answer ...
1. If another user has some signatures is there a way to see how much the user has earned from the sigs?
Ask the manager LOL
common sense - learn how to find their wallet address and check the address if they have one.
2. Are higher ranked users, Legendary, Full Member, Member, paid different rates for carrying the sigs?
Depends on the manager.
Another commons sense - Normally yes, it's different rate.
3. If a user ignored the May 24, 2015 direction to change his password, had a higher than Jr. Member status, and had his username hijacked, and the hijacked username now has a string of sigs, and the ethernet address posted shows large amounts of eth moving through, is there anything the real owner of the username need to worry about? If he's in another time zone on another continent will that disrupt my sleep or would that be something to do with the large amounts of eth moving through?
Not very clear but I do not see a bitcoinTalk account and an ETH wallet will have any connection at all.
Common sense - BitcoinTalk is not a currency or wallet
Who is soy by the way?
