Roomba, i.e. the system that takes care of automatically deleting supposedly low quality questions, is used in both main sites and meta sites. However, in meta sites, the voting system is different: people may downvote questions when in disagreement with the standpoint presented in the questions, despite the questions be of interest. But Roomba automatically deletes downvoted questions (with a few more criteria). Should Roomba have customized rules for meta websites, since the voting system is different?
For example, we could remove the Roomba's criteria on downvotes. Example of useful meta questions that it would save: https://lifehacks.meta.stackexchange.com/q/2679/12
