So if a mod moves or deletes a topic where 50 people have posted, he'll have to send 50 PMs ? Really ?? And also send a bouquet of flowers or a box of chocolate to apologise too I presume?
I'm going to be direct, I (as usual I'm speaking for myself, but I'm sure my colleagues are on the same page) don't give a damn about the post count when I delete/move a post/topic. There are no rules, no instructions from Theymos on this subject. Before clicking on the 'Post' button, it's up to you to decide whether the topic has a chance of being moved/deleted or not.
But we have to agree that a notification for having one of your posts deleted would be a nice feature. By way of not having it bitcointalk lacks a feature many other social platforms would have as standard. By this point it might be wishful thinking to hope such feature gets implemented but one can only hope.
