"Self-sourced" as in both of our comments are hearsay: we say we heard this information from someone and our source for that is only us saying so. That's pretty bad in terms of what others can actually do with that information (from either of our comments). Not just because hearsay can be faked, but more because it's unquestionable, untestable, and the quality of the information has almost always greatly degraded compared to the source.

This doesn't mean the comments should be assumed to be false any more than they should be assumed to be true. It also doesn't imply we necessarily have some way to provide an actual source either. Just that folks will have to go elsewhere if they want any certainty about this information, since we didn't provide any as random usernames on a message board saying we heard something before.
