I don't think this is something to implement on DT1 selection since signature campaign isn't directly related with forum administrators. The simple solution is as @suchmoon said simply ~distrust the user who wear paid signature. If in case implement your expected points then most likely maximum DT1 will be red tagged users. Its because most of campaign manager doesn't accept red tagged users.
Is this because nobody wants to hire the Turkish monkeys into campaigns?
