Rumor would mean that I don’t have personal knowledge. I do. It is not a rumor, but rather an anecdote, and the source will remain unknown and unposted. I appreciate your reply.
You claim to have anecdotal knowledge. That may be true! But when you anonymously post that claim to the internet, it is a rumor.
I think we agree: in my personal context it is an anecdote but let’s use rumor in this context instead.
