I personally think that in this case, its somewhat a good idea to have a general guide to this issue.
My reasoning is this. Whether or not the behavior is malicious or not isn’t the issue I think, not really, its the cause. The actual issues are or rather the question to be asked, is: Where is the line between nuisance and acceptiable behaviour?
Removing the intentional vs non-intentional leaves behind a simple problem. Of which, having a guide that can help specify when something becomes a nuisance can mean that moderators have more control over a situation that they perhaps don’t have a great deal of control over as it is in this moment.
