Integration Test - DDOS Try Many Small Miners

[ASuciuX]

Could a lot of small miners, each spending 0.1$ worth of BTC per block, do anything malicious to congest the communication/network? All of them submit valid transactions (valid blocks etc.) but they submit them as many times as they can in order to create a lot of noise. All of them are run by the same bad actor.

Question: Any node could write messages to the StackerDB (miner/follower) ? What are the limits? Kind of related to https://github.com/stacks-network/stacks-core/issues/5122
