I'm also a serial offender for not using the survey tag, but again, I upload all my traces.
I do a bit of yahoo tracing as well, and don't directly mark that either... But then again, I don't go and screw around with any existing nodes and ways unless I've been there... however I have been known to add the road way in off a random trace that wasn't mine if I've been in the area (sans name generally) and the trace quality is good enough. It's an intractable problem - forcing a source=survey/yahoo/made_up tag still won't solve the issue as the source tag needs to be kept up to date, and you can link the source tag to the individual tag within a node (eg: the way is yahoo sourced, the name comes from the MMBW maps, a local marked it one way through local knowledge, and someone added speed humps using a GPS trace/waypoint setup. So the source tag contains a variety of sources, and no way of determining what applies to what. In the end, the crowdsourcing approach *should* sort out the wheat from the chaff eventually, but no doubt there will be some hiccups along the way.
