Separation old trust system into trust flags help to distinguish things, and therefore don't make people become mad for their different levels of mistakes. Flag gives other options, because there are little DT members whom use neutral trust for non-serious issues. Flag, with newbie warning flag, is an alternative. With separative usages of trust flags, drama will be reduced.
OP, it is good to see you started as reading forum rule, so you stole one of my smerits. Congrats.
