I have translated the report on huwiki’s experiment of disabling the Flagged Revisions feature of hiding unreviewed changes. Here is the tl;dr version, see the link above for the full report:
We looked at two questions: 1) Does the partial disabling of flagged revisions help with the problem of editor decline / stagnation? 2) How much extra load does it put on patrollers? (The third question would the frequency of readers seeing vandalized content, but we did not have the capacity to calculate that.)
- The number of anonymous edits increased by ~30%; the number of anonymous editors by ~100% (although by the nature of anonymity, the latter is less reliable). We did not see any other effect: there was no increase in the registration rates; there was a slight increase in the number of edits by active editors and by logged-in editors, but it’s hard to see it as a trend (the increase started a few months before the config change). So it seems that there is little impact on the growth of the editor community; in the future, if we find a good way to convert anonymous editors (e.g. with targeted messages after they edit), it might increase the efficiency of that.
- The ratio of bad faith or damaging edits grew minimally (2-3 percentage points); presumably it is a positive feedback for vandals that they see their edits show up publicly. The absolute number of such edits grew significantly more than that, since the number of anonymous edits grew; the two effects together resulted in about 500 extra vandal edits and 800 good-faith damaging edits per month. The number of productive anonymous edits increased by 2000 per month. (Before disabling, the status quo way about 1000 vandal edits, 2000 damaging non-vandal edits and 7000 productive edits anonymously per month.)
