If the shock is bottoming out then there is no movement in the shock anymore. This means that it is basically a solid rod transfering all the energy straight through. If it doesn't damage the shock it will eventually break your shock tower or crack your frame.
Lower your bump stops a little.
Didn't think about that, that's how I ripped my shock tower off when a front shock siezed on Swap last year. The tower does not make a very good bumpstop, it's not designed to take the load.
