Hi David,
You make a valid point and this is something that we've definitely discussed within the Community Team as well several times. We continuously try to improve our rules and policies. You might have noticed that our
rules page was recently revamped. Some old unnecessary rules were removed and others were reworded.
Now, with regards to the bumping rule. We're actually already way more lenient with that than we used to be, exactly for the reasons that you mention. We decided to keep the rule for now though. This is because we still want to be able to disallow users from making five or six posts in succession, even if they're adding new information. We still don't want to see a new post for every single new sentence or every tiny new bit of information, so to speak.
It's currently at the discretion of the moderator looking at the report, or the topic in general, whether to kindly remind the user of the bumping rule or to let it slide in that specific case.
