At best, the process is cumbersome, which inhibits use/traffic/activity.
As for allowing the debate to continue in MilesBuzz where it first erupted or not, we run into the essential quandary being discussed: move the debate to the Suggestions board and it dies and doesn't/won't get the traction/feedback it deserves.
Maybe it can now be effectively moved because it has exposure/involvement, but moving it is still is likely to impede participation/feedback from new posters vs. rehashing by the same group of posters that has already expressed their opinions.
In addition, locking these discussions is likely to further fuel the flames...even those that have mentioned that the topic does not belong in MilesBuzz and are FOR aggressive moderation have tended to do so in a tongue and cheek fashion.
I support leaving these threads open here to provide maximum exposure and invite the widest possible feedback.
