I went to fix an obvious typo in someone's post, and was unable to do so due to the six-character minimum. I'm new to this site, so I want to understand why.
I've read What defines a necessary one-letter edit? Standbuck's answer explains the consequences of "edit spamming." The post a few years old and seems to imply that one-character edits are allowed, although too many of them are discouraged.
Has this policy changed, so that fixing an obvious typo is now disallowed? If so, that seems counter to the ideals of a site about writing, so there must be a practical reason for it. Can someone explain, please?
