Problem: A multitude of tools make mass edits possible, which is nice. But sometimes errors happen and it seems like some erroneous (mass) edits stay in our database just because it's such a big turnoff to go through hundreds or thousands of edits manually.
Who would benefit: Wikidata editors, data quality (i.e. Wikidata users)
Proposed solution: It should really be as easy to revert your changes as it is to do them in the first place.So I guess we need a tool that lets you select in an intuitive way exactly what (own?) changes to revert, e.g. by exact period of time, by patterns in the edit summary, ... or maybe just by easily preselecting (and deselecting) some items or ranges of items from a list with single clicks/keystrokes before initiating the mass revert action. Integration into the Wikidata website would be nice.
QuickStatements can be used to mass-remove statements. That combined with SPARQL queries allow you to build a query that catches all the bad statements and than build list of QuickStatements commands to remove them. How would your proposed toll be different? --Jarekt (talk) 15:43, 15 November 2017 (UTC)[reply]
QuickStatements usage for this purpose is far from intuitive and as a result many people don't use it this way. I think it would be great on Special:Contributions/ there would be a way to undo all edits you have done between time X and time Y. It should allow everybody to undo his own edits in bulk. As far as undoing others edits in bulk I'm less sure. We might give that feature out along with the rollbacker permission or even limit it for admins.
