I posted what with hindsight I now see is a controversial question:
I think the question is controversial in the sorts of answers to the question that it's appropriate to give, and perhaps also in the legal status that providing answers to it might entail. I'm no SE insider, but I get the impression that controversial questions are frowned upon. Some answers were deleted. I think the deleted answers were not controversial in their statistical content. Rather, it was controversial more along the lines of whether it is appropriate to provide any direct answer at all.
The four or so answers that were deleted discussed relevant statistical ideas. Of the two answers that remain, neither discusses statistics. Instead:
One (the top-voted answer that remains) gives -- what to me as a layperson is -- legal advice (not legal advice in any legal technical sense, because I don't know how that is defined). That advice appears to be incorrect for my country.
The other gives a controversial opinion about how the legal system does or should work.
I think those remaining answers are poor, for the reasons above, and also give the misleading sense that they reflect a consensus view. The deleted answers make clear that this is not a consensus view. Rather than leaving the question in its current state, I think it would be better if the question and all of the answers were deleted.
So I have two questions:
Can I / should I delete the question? Might it come back again in some partial form (for example, with only some of the answers present, as now)?
How can I find out why and by whom the answers were deleted?
