I just got this email as well. The reset link leads to a similiarly named site, but not itch.io. It looks convincing, but that I found nothing on the itch.io website about this alleged data breach made me suspicious.
There has been no data breach on any of our services that we’re of. Most likely a scammer who happened to find an email somewhere and trying to use it to steal your account.
If happen to have this email still we would like to see it. We want to see the details of the sending account and the contents of the email.
