One stupid question,

If miners put some shit in blockchain because they are free to.

If most nodes reject to validate this shit.

What will happen to the blockchain ?

1- another new block from another miner will be used instead (a more clean one) ?

2- or miners will continue to mine shit block with the few nodes validating them.

I want the reply to be clear, if there is a vision's battle between nodes / miners who could win / loose and what is the consequence on the blockchain integrity and future ?
