Ok if people on the top ap earners list (myself inc) can close a thread (make it suicidal) with only a few meg assignments where is the point in mods?

any top ap eanrer (or high earner)n can target a thread and close it which aint really fair as it should be a community decision to close a thread not one person

so can we have it that even though neg points are assigned once you have assigened negs to a thread the person you assigenedd them to still recieves them but after first assignmanet they do not effect wether thread goes suicidal or not???
