Admin Forum:New users without user creation log or edits?

I was wondering why there are new users, and user avatar additions, without upload log activity, or local files, or user creation log activity, or contributions? Shouldn't new users only appear when they edit something, or create an account on the wiki they're on at the time they create it? -- 76.65.128.252 08:05, August 31, 2012 (UTC)
 * There is no contradiction in what you say. I can go to another wiki and do nothing but change my avatar. So?--PedroM (talk) 13:10, August 31, 2012 (UTC)
 * I was wondering why they showed up in the activity log. -- 76.65.128.252 03:12, September 1, 2012 (UTC)
 * Well yeah, normally you do not share a user database over many wikis, so that's why these things happen. "Fixing" it would probably break something else, so not keen on another MW hack.--PedroM (talk) 03:25, September 1, 2012 (UTC)
