Every faction (or faction family) will have their own system for war payouts.
A good reputable faction will keep around 20% and payout the rest and will use the faction cut to fund weapons, armors and other stuff for its members.
Some pay based on hits, some based on respect, some have more complicated systems.
For example, our faction pays based on hits, but we do penalise low FF target hits.
There are tools for catching bleeders and again it varies per faction.
In fact, there are tools to monitor basically everything and its up to the faction leadership to decide what and how they monitor and penalise for.
The bigger the faction the more sophisticated its tools are for these things.
