Hi everyone,
I’m looking for statistics about the edits that are reverted on the English Wikipedia.
This is for purposes of explaining to the public what Wikipedia’s quality control
processes are like. If hard numbers aren’t available, I’m also interested in educated
guesstimates.
1) An often-quoted statistic is that 7% of edits are reverted. Is this still believed to
be true?
2) According to
https://blog.wikimedia.org/2017/07/19/scoring-platform-team/, 2.5% of
edits are vandalism. There are other common reasons for reverting, and I’m wondering if
anyone has studied their frequency. Does anyone know what percentage of all edits are
reverted for being:
a) Spam (as perceived by the reverter)
b) Copyright violation
c) Violations of the Biographies of Living Persons policy
3) Do statistics on the number of edits per day on the English Wikipedia (i.e. 164,000
edits per day) include edits that are blocked by the spam blacklists or by edit filters?
4) How many edits per day on the English Wikiepdia are prevented (blocked) by the spam
blacklists?
5) How many edits per day on the English Wikiepdia are prevented by the edit filters?
6) What percentage of all reverts are made by users of Huggle and Stiki?
7) What proportion of vandalism is quickly reverted? A 2007 study (Priedhorsky et al)
found that 42% of vandalistic contributions are repaired within one view and 70% within
ten views - have any newer studies been done on this?
Thanks in advance!
