Machine translations of [[User:Irus]]
Deleting doesn't have any effect, you'd better retranslate any newly translated message which you think it worse than nothing. As for rollbacks, are you sure everything needs to be rolled back? How many messages did you check? I can make you sysop temporarily, but tell me how much time you need.
Until all his new messages are re-translated, English versions are much better then Irus's versions. I sure that many of his edits need to be rolled back, maybe all /ru-edits. I check many of his /ru-edits and almost all of this is nightmare horror. I think this weekend will be sufficient.
Ok. If you can't check every single translation before rolling back, try at least to sample them. Sometimes, or in some message groups, there might have been some logic.
Deletions don't have any effect because FuzzyBot will reimport the exported translations on the very next day. One would need to first remove the translations with a patch to the MediaWiki extension or other project. It's vastly faster to retranslate.
Is it possible to filter from his contribs only /ru-pages?
MaxBioHazard, did you give a look to the remaining messages and what needs to be done here still?
Basically I did what I want, if you want desysop me, you can did it.
