Okay, I know we've discussed this before, but I really think the stance of "whatever, as long as the copyright and character are tagged" is completely wrong. Exhibit: post #642770
This is the tag set after Mr_GT uploaded it:
? + – blue eyes 81076
? + – blue hair 47765
? + – hair bobbles 3414
? + – hat 59945
? + – kawashiro nitori 2559
? + – short hair 107740
? + – solo 63776
? + – touhou 117665
? + – twintails 49139
Notice how the least populated tag in this set has over 2.5k posts. This kind of tagging is damn useless. The picture has a metric buttload of fairly uncommon, easily-identifiable features. Cucumbers, bucket, shoe dangle, sweat, hot, bikini under clothes, screwdriver. But none of them were tagged, and thus none could be used to find it later.
Thus I will go, once again, against the current acceptable tagging policy. We should absolutely require all the easily identifiable, uncommon generic tags to be present in order to consider a picture properly tagged. And before somebody goes "so I need to invent tags for post #388625 now?", no, that's the entire point. We have more than enough untaggable pics already, which is why we positively want to tag all the ones that have some sticking points. (Though in all fairness, adding smile, braid and sketch to it wouldn't hurt).
