Locking a post has very severe consequences for a post, you cannot
- Upvote or downvote on it
- Edit it
- Vote to close or reopen it
- Comment on it
- Add new answers to it
Because of these severe consequences I usually avoid locking altogether and try to deal with the problem in other ways. Locking just has far too severe side-effects for my taste, I don't want to prevent anyone from voting or answering just because there is an edit-war on the post.
We now also have some locking reasons, ignoring the historical significance reason as it isn't relevant here, they are the following:
This post has been locked while disputes about its content are being resolved. For more info visit meta.
This post has been locked due to the high amount of off-topic comments generated. For extended discussions, please use chat.
Both are common reasons for locking a post, and in both cases the locking is there to prevent only a small subset of what locking actually stops.
Those locking reasons shouldn't only be a text attached to the lock, but they should also change the behaviour of the locks:
- A lock for off-topic comments should only prevent new comments
- A lock due to an edit war should only prevent edits to the post
This would make using those locks less disruptive, and more useful to moderators.
