Moderators, just like members, build up relationships with sources. Sources sometimes take advantage of this relationship..(former mods have rarely done this too) a moderator will not know for weeks, maybe months that a source has gone bad... though most times it is faster. Obviously sources offer discounts and even front stuff to mods, or to POPULAR members. Though I dont know of any mods, that are still on this board, who have abused that to refer people to scammers, even selective ones.
KEEP IN MIND THAT, UNLESS THE MOD HAS PERSONAL IMMEADIATE CONTACT WITH THE SOURCE, IT IS VERY DIFFICULT FOR A MODERATOR TO KNOW THE CONDUCT OF SOURCES...UP TO THE MINUTE.... THEY DO THE BEST THEY CAN..
AS FAR AS PRODUCTS... PREFERENCES VARY... A LOT... some people love chinese (mostly for fiscal reasons) others would rather mass inject brovell...
