Edit:
excess funds have been returned for both Kusama and Polkadot:
We propose to showcase Polkadot’s high scalability in a real-world setting by submitting enough transactions to completely fill blocks for ca. 30 minutes. To do so, we require DOT to pay for the transaction fees plus to temporarily finance some existential deposits (EDs).
At least 80% of the DOT spent in fees through this proposal will be returned to the treasury (see: https://wiki.polkadot.network/docs/learn-polkadot-opengov-treasury). We will also return any excess DOT remaining after spamming transactions or DOTs used for temporary EDs.
Amforc takes no cut for conducting this experiment. For full disclosure, as Amforc operates validators on Polkadot, these validators may occasionally collect part of the transaction fees.

Following community feedback, we have decided to submit a parallel referendum on Kusama that would be executed before this referendum. Should any bugs be revealed on the canary network, we will hold off on spamming Polkadot until those are fixed, or return the funds if revealed bugs cannot be fixed until December 20, 2024.
