I'm sorry, I am not going to get into comparing one thread with another or any of this "why was this done but not that". It is impossible to achieve 100% consistency and all topics are different after all.
Every situation comes down to being a judgement call. Ultimately, people have to accept the decisions that are made and I hope will appreciate that they are being made for all the right reasons and intentions.
Some will not like the fact that moderators do have more freedoms than others but this comes with the job I'm afraid - it would be very difficult if not impossible to do otherwise. Yes, we can lock threads but rarely do. Sometimes we have to lock things we have commented on or also started and again, it's a difficult tight-rope to walk.
Of course, I'd hate to fall out with waiting being one of our most long-time posters 'n all so I hope we can just disagree on a few points.
