A couple months ago, it was brought up that we should really figure out what to do about the outstanding [identification-request] questions. The immediate impetus for this was probably the realization that [identification-request] was showing up on the front page as one of our top tags despite being blacklisted. Thankfully, this was fixed pretty quickly. However, the question remains: what, if anything, should we do about the remaining id-reqs?
In this post, Logan proposes (as option #4) that they all be retagged to use the tag of the series in question, with the identification-request tag removed. For example, What manga is this image with a depressed girl from? would be retagged to watamote. Gao posted another answer in support of this solution.
I propose that we implement Logan's solution. Note that this will require moderators to do all the retagging, since all the remaining id-reqs are historical-locked - but I'm willing to spend the time doing this, and the other moderators can of course spend the time if they'd like as well.
If, after a suitable length of time (say, a month or so), people are in agreement with this proposal, I'll start retagging the id-reqs (in small batches, so as not to flood the front page with crap).
This does make it non-trivial to identify the id-reqs that survived the Great Identification Request Cleanup of 2016... unless you use the power of SEDE.
Update (8 Feb 2017): Given that it's been a month and nobody seems to be opposed to this plan, I'm going to start retagging [identification-request] questions in small batches.
