I lost my account

I don’t play Rust for a few months, now i’m trying to log in - User not found, ok so i click forgot password and write every of my emails - user not found, i’m trying again and again - Your IP has failed too many times. Try again later.
What i should do, i lost my account for ever?

yes, accounts which were inactive were deleted.
the concept is alpha testers get to keep the game upon release.
not people who registered when it was open and come back 4-5month down the road.

alpha keys will be available in a few weeks for purchase (limited daily) come back then
