Additionally, if we used the same hash function as for new edits, it would make it pretty trivial to figure out what most of the hashes are. I think its safe to say we wouldn't modify old edits. After all, you can still look at https://en.wikipedia.org/wiki/Special:Contributions/216.143.215.xxx despite us not using that scheme anymore. --bawolff _______________________________________________ Wikitech-l mailing list [email protected] https://lists.wikimedia.org/mailman/listinfo/wikitech-l
