This is of course possible, and I don't object that as long as they know they are reiterating. However, this is only possible if people at least skim over previous posts, which is usually not the case, and which is why hints to previous discussions are not only helpful but necessary to avoid wasting time.

Repeating something for didactic reasons is sometimes indeed no waste of time for the writer. However, if the writer then publishes this, despite other people already wrote that stuff up in a much better way, that person wastes the time of the readers by filling up the comments with, let's face it and call it by its name, garbage.
