In reply to tlouth7:
Is there actually any detriment to having feedback posted that is no longer relevant or else that is posted erroneously? Personally, I would prefer it not to be the case that other users can ask for feedback to be deleted, as it basically creates the new problem of someone or something being responsible for deciding which feedback to keep and which to delete.
Some information, e.g. out of date conditions report, may be useless from the perspective of current conditions and therefore flagged for deletion. But, from a different perspective, e.g. curiosity about conditions in previous years, it may actually be interesting and useful data.
A further point, is that it is only through feedback that users with hidden logbooks can make a public note, e.g. loose as hell, undervalued route, sandbag. I realise that a strict interpretation of the rules means these comments on difficulty or quality shouldn't be posted, but the ratings system is useless and there are many reasons why someone may prefer a hidden logbook, not least that it allows them to keep a personal record of information that is not for public consumption. The system you are describing basically forces users to have a public logbook or lose their voice.
I would also add that I doubt it can simply be added to logbook notes, as the user will already have a log, possibly with a note.
