I haven't logged in for a while now into my account, perhaps around a year, only to discover that I was greeted with the following screen:
I continued to "Confirm my account", even though I have posted a number of questions related to measure theory and probability theory in the past, so my account was already set up, only to discover that all my reputation is gone, and even worse, all my questions and their answers are gone. How can this be ??!!
Even more annoying is the fact that some of those answer I received were pretty important to me, and I haven't saved any links or keywords regarding them, so I can't even find them on the site. For example, now I'm dealing again with some measure theory after a timeout and I'm not sure if I may have asked that question already or not, and wanted to look up my old questions, where I might have already asked about that. But they are gone.
(Weirdly, what I posted on stats.stackexchange.com seems to be there without any issue. Note also that the account under which I'm posting this is the account in question. To recap: I can log in to my account with my old password and email, but all content that I generated on math.stackexchange.com with this account is gone.)
