A not-small percentage of proposed edits are from anonymous users. I'm not sure how this works. It's not Community because that would be a high level user setting that name, no? And why do an edit that way?
I suspect these are non-users of the system proposing an edit. There appears to be no minimum rep level required to propose an edit (only to have one go through without approval).
Honestly, I reject these as general principle. Someone who hasn't even taken the time to create an account is trying to edit posts? Even when they're reasonable edits, I just can't get past the source.
For example, here's one that just came up for approval. I don't have a problem with an edit that adds a link to a reference, though I feel that the author should choose which reference to use. My issue is that the user isn't a member of the community.
Am I missing something here? Who are the anonymous users? Could it be, say, the OP who just wasn't logged in properly? Or is it a moderator? Or is it indeed some random passerby?
