This is something we recently started doing. If email sent to your email address bounces with an error message like, "This email address doesn't exist", then your email may eventually be changed to u...@bounces.invalid. (It's not possible for users to change their email address to something ending in .invalid, so this can only be an administrative change.) Because your old email didn't exist, somebody could've registered your non-existent email address and used that to steal your account.

That means that majority of old inactive accounts could soon have changes email addresses in the same way.
It's a good security measure but it would be better if this was announced before it started happening, maybe some members would do manual change.

I wonder if op was using gmail? because google has recently started deleting inactive accounts

Exactly!
I was thinking the same thing, and they also deleted ALL old cache links, so you won't find anything old from bitcointalk anymore!

Anyone who wants to research old Bitcointalk pages can still do it here:
