2- Like stake has hired some puppets, you need to hire some trusted members. Yes it costs money but look they defend you against all the victims and go as far as tagging the victim himself as one of the stake puppet does.
Unfortunately, anyone who joins the 1xbit signature campaign automatically receives a negative trust. I think that 1xbit campaign manager would be very happy to accept users with a positive or at least neutral trust to the campaign, but no one wants to risk make their rank worse.
