Not sure if this has already been discussed here, so here it goes. Often, when reviewing the *Late Answers* queue, I run into some answers that seem to be posted many times by the same user

I understand this is probably because their author find a solution to a problem that hasn't been documented/answered yet, or they consider valuable, or maybe it's something hard to find, etc., so they post it many times on different questions.

Examples [here][1] and [here][2].

What shall be done when this happens? Should I flag one of them (probably the latter) so it's deleted and advice the user to simply quote the first one? Is it ok to have both?
