I must, respectfully, disagree with you on a couple of points, Ray:
You should respect the sensitivity of others and respond to their questions and requests - which you cannot do if you orphan profiles immediately after creating them.
Whyever not? Anybody can click on the Changes tab and see who created a profile, even if it's been orphaned. So anybody who wants to ask a question can do so. (Although I have had a couple of requests from people who were wanting to write papers on long-dead notables for whom I had created profiles. The writers assumed that I have vast stores of knowledge about those people, and was choosing to hoard it. They weren't too happy when I answered, "All I know about this person is what I found on Wikipedia [and Find A Grave, FreeBMD, Library and Archives Canada, or whatever sources I found] and have put up on their profile.")
As for requests, that's easier still: since the profile is orphaned, a family member can adopt it with one click, and take it private if they want to. (Well, unless the person died long enough ago that that's not an option any more, but that time limit is so long that nobody could possibly have a memory of that person.)
There are far to many profiles in WikiTree already that are incomplete and inaccurate and we don't need more.
I'm going to assume that you mean that we don't need more incomplete and inaccurate profiles on WikiTree. Because if you're saying that we don't need more profiles at all, then I am really going to have to take exception to that. As of the beginning of March, there was one profile on WikiTree for every 2,754 people born since 1 AD (give or take a few). We have 32 branches (that I know of) with 500 or more profiles in them which are not yet connected to the main tree. Some of them have been unconnected for years. I have long been of the opinion that one of the biggest reasons why people join WikiTree, add all of their family tree that they know about, and then leave is because it takes so long to find connections to the main tree. The more profiles we have, the easier it's going to be to make a connection. It's already easier than it was four years ago, when there was only one WikiTree profile for every 5,729 people, but it could be much easier than it is. Especially when we're trying to build a single tree for everybody in the world, the "network effect" is huge.
That is why I am very much in favour of more, more, more profiles. I don't want to lose potentially valuable volunteers because of that frustration, because I'm not sure we'll ever get them back. (Has anybody in this thread joined WikiTree, given up because they couldn't make a connection, and then come back again? If so, could you please tell us what we did that motivated you to come back? Because whatever it is, we should probably do more of it.)
Of course, I'm also very much in favour of accuracy. But, in my opinion, discouraging people from starting new profiles is not the best way to achieve accuracy. For one thing, there seems to be an unspoken assumption that most profiles (new or old) are wrong in some way. Incomplete, I will absolutely grant you. But in my experience taking part in the Sourcerer's Challenge, the vast majority of profiles don't actually contain inaccuracies, but simply don't have the sources to demonstrate that the data in the profile is actually accurate. It's very rare that I have had to change, say, a birth date or place. (I would imagine that the experience of Data Doctors would be very different, but then again, Data Doctors are only looking at profile with suggestions on them, so their view of the health of WikiTree as a whole could be somewhat skewed.)
To me, the solution is to make new volunteers welcome, encourage them to put up their family tree (at least, as much as they know), and teach them how to find and document sources. The more success they have in things like proving the facts about their family, and connecting to the main tree, and the more pleasant their time on WikiTree is, the more likely it is that they're going to stick around and start working on those incomplete and inaccurate profiles that are here. To bring all the profiles on WikiTree up to the quality we want is going to take a lot of work, and a lot of time. The more volunteers working on the problem, the more person-time is going to be spent on it, and the less calendar-time it's going to take.
