Hey there. We just wanted to chime in that you can avoid the account closure by logging into your account within the 30 days (since receiving the email pictured) and selecting the Cancel Account Closure link contained in the email. We certainly do not want you to lose access to your games or account so if you have any difficulties logging in then please create a support case with us. >> ubisoft.com/help
They said if you receive an email, it's 30 days of no activity once you receive the email. Apparently it's being sent to people who have been inactive > 1 year.
Still bullshit, you could be in prison, in a coma, travelling the world or just not gaming for a while and want to come back to it. I know I can go months without playing games and then picking it up again.
