N4G's version of Twitter's Community Notes

Even though N4G lost the old bubble system, which also enabled users to give +/- bubble votes, I think a good return to that would be something like Community Notes. Instead of petty quarrels inspiring a marked-down comment, it'd be great to have a mod-exclusive ability that'd contest fact claims made by users w/out resorting to outright marking it inappropriate. The comment would still be up, but there'd be a little box correcting them that's attached to the comment. I dislike fanboy misinformation, but if they're within the guidelines/TOS it should stay up and be challenged. In order for N4G Notes to work, said mod would HAVE to provide a source as well.
