Meta Stack Exchange is where users like you discuss bugs, features, and support issues that affect the software powering all 157 Stack Exchange communities.

What is meta?
Here's how it works:
  1. Any Stack Exchange user can ask a question
  2. The community provides support, votes on ideas, and reports bugs
  3. Your voice helps shape the way Stack Exchange operates

In particular, several users all have the same gravatar. Yet the have different reputation scores, etc.

I thought the gravatar was an MD5 hash of the users email address. Thus I don't get how there can be all these duplicates?

alt text unknown,unknown,unknown,unknown,unknown,

Just curious...

Nice gravatar, by the way. – Bill the Lizard Aug 14 '09 at 1:11

The generic gravatars are generated from the user's IP address, not their email address.

Do all the users come from the same IP? If so, why aren't they merged? – Kyle Cronin Aug 14 '09 at 0:54
They aren't necessarily the same person. If you and I work at the same company, or just have the same ISP, we're going to appear to have the same IP address from across the Internet. – Bill the Lizard Aug 14 '09 at 1:02
...but, yes, I did check, and all of those users do have the same IP address. – Bill the Lizard Aug 14 '09 at 1:02

Interesting. I merged all these users since they are clearly the same entity.

In the future, you can just flag any post by this user for mod attention and let us know -- unless you want it to be a discussion topic in and of itself here on meta.

Probably not a bad idea in this case to have the discussion; we do reserve the right to merge accounts that are obvious duplicates.

Nothing keeps two people from having the same nickname.

but the nickname is not the source of the gravatar :) – warren Mar 6 '10 at 15:32
