Longer term, what do people think about multi-stage proposals? Something like Multi-stage Governance Proposals, Starting w/ Stage 0 and Stage 1
There could be a 1 ICP fee to submit a proposal to stage 0. Progressing to stage 1 could have a higher fee but by then the people submitting could gauge whether that seems worth it based on the feedback from stage 0.
Individual users could decide if they want to see stage 0 proposals by default, which could help filter out spam.
