Gov Spam Prevention Mechanism

[glnro]

Summary

A spike in spam gov proposals has necessitated a temporary mitigation until the Hub can upgrade to v0.47 of the SDK which will include enforceable spam prevention via the addition of a gov param for initial proposal submission deposit..

Problem Definition

At present it costs next to nothing to execute a spam attack via governance on the Hub. While the only nuisance to the chain it causes is driving a sharp increase in the gov proposal index, most of these text proposals include malicious links that have the potential to harm users who might be unaware.

Proposal

Create a new ante decorator that filters messages for MsgSubmitProposal, and returns an error if the minimum deposit threshold is not met. This MinInitialDeposit can be a hard amount, or a percentage of the MinDeposit. Current MinDeposit is 250000000uatom. Something like 10% would put the price to submit a proposal between 300-350$ at the time of writing.
