.... but really it is not up to users to start getting over involved in moderation.
This. ^ ^ ^
Moderators have access to resources that we members do not - and those resources allow them to look a lot more intelligently at members and posts. This gives them a much better knowledge base upon which to make decisions.
As members, we should report things of which we have concern and then let the Mods do their thing. Members trying to do moderation is like trying to match paint colours in the pitch black of a basement on a moonless night.
