It was WHL & me. On every Wikipedia page there is a history link, that shows every edit that's been made. Click on the "prev" link to see exactly what was changed.It looks like someone may have read my post from the other night (one of the many posts that unfortunately disappeared due to the "glitch" that occurred) and changed Geelong's Brandan Parfitt's DOB on his Wikipedia page.
If it was someone here thanks a lot for doing that. I was about to point out that it still wasn't quite right, as it said 24 April 1998 when it should be 27 April 1998, but it's just been changed again to the correct DOB!!!
A while ago I made a list of all the articles with a mismatch between afl tables and Wikipedia (will Wikidata actually, as you can't easily scrape dates of birth from Wikipedia articles, but they should match)
