# Reputation Spamming an MEV auction with optimistic transactions that have a low probability of success may be profitable if the costs of transaction failure are low, or the auction offers free reverts. To efficiently use block-space and gas in a permissionless Atlas auction, the Solver Operations included in the `solverOp` queue may also need to be prioritized in some way. Our approach is to give apps, networks, and infrastructure providers the data necessary to easily implement their own solution. The Atlas smart contract makes historical data available for each solver to assist developers in this filtering: * \# of auction wins * \# of failed Solver Operations * Total gas used by all Solver Operations Application developers can define their own formula to interpret this data, as well as other data they may want to collect, to create a `reputation score` for each bidder. In the simplest version, `reputation score` can just be the Solver's historical success / failure rate, which is directly readable from the Atlas smart contract. You can dedicate as much space as you would like in the `solverOp` queue to bidders of a certain `reputation score`, or allocate space in more complex ways. That is completely up to you and can easily be tweaked over time; it is not enshrined in Atlas. --- # Agent Instructions: Querying This Documentation If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question. Perform an HTTP GET request on the current page URL with the `ask` query parameter: ``` GET https://fastlane-labs.gitbook.io/atlas-draft/building-atlas-modules/reputation.md?ask= ``` The question should be specific, self-contained, and written in natural language. The response will contain a direct answer to the question and relevant excerpts and sources from the documentation. Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
