I) In 99 percent of the cases, the [tag:homework] tag runs smoothly and as intended. In a few cases, OP does not agree with labeling his question with the [tag:homework] tag; often it's a new user that hasn't read the [wiki description](http://physics.stackexchange.com/tags/homework/info) or the [site policy](https://physics.meta.stackexchange.com/a/715/2451), but sometimes OP is right and the [tag:homework] tag is removed again from the question with no further discussion. II) In the early days of Phys.SE, whenever there was posted a homework question without the [tag:homework] tag, then the moderators would politely ask OP if this was homework or not? Typically, a couple of full answers to the homework were posted and accepted before the issue of whether or not to add the [tag:homework] tag was settled. Thus OP would succeed in getting a homework solution from our site, which in other respect is mainly dedicated to just _conceptional_ physics questions. III) In the last year or so, the tagging practice was changed, and users with tagging privileges would now often add the [tag:homework] tag whenever they felt it was appropriate _without_ first asking OP. The answers were now typically just hints, advices, outlines, etc., instead of full solutions. So the [tag:homework] tag clearly had the desired effect. Moreover, this new practice didn't seem to spur repeated back-and-forth edit war over the [tag:homework] tag. Typically it became clear to everybody whether or not the [tag:homework] tag would apply in a given case or not. IV) _If it ain't broke, don't fix it._ I fear that by banning the [tag:homework] tag, we in practice loose a useful user-based moderation option, and effectively turn this site into a homework help service. V) Another aspect is that many of our readers use the [tag:homework] tag to decide whether or not to read a post. This goes both ways.
