There has always been a debate about vandalism by anonymous editors. On this page, just for the sake of passing a little time, I'm putting together some stats. The shocking conclusion of my study is that anonymous edits are 7,842 times more likely to be vandalism than edits by logged-in users.

Facts from other studies edit

From Wikipedia:WikiProject Vandalism studies/Study1:

  • Anonymous editors are responsible for 97% of vandalism
  • 4.6% of all edits are vandalism

From my own previous study User:Cool3/Analysis

  • Anonymous editors are responsible for 87.2% of serious vandalism

From Wikichecker's edit rate

  • Generally, edits on Wikipedia average about 8,000 per hour
  • In general, anonymous editors account for roughly 30% of edits; registered users account for 70%.

Basic math edit

  • 8000 edits per hour*4.6% vandalism = 368 vandalism edits per hour
  • 368 vandalism edits*97% anonymous = 357 anonymous vandalism edits (368*87.2% anonymous = 321 anonymous vandalism edits)
  • 8000 edits * 30% anonymous = 2400 anonymous edits
  • 357/2400 = 14.9% of anonymous edits are vandalism
  • 11/5600 = .0019% of registered edits are vandalism.
  • 14.9/.0019 = 7842. Thus, according to the data here an anonymous edit is 7,842 times more likely to be vandalism.
