How long does it take for a account to Expire?

I am off Chess.com ( Correspondance Chess Play ) for I don't know how long.
Wanna try and beat some Chess Program.
How long does it takes for my Account to Expire and to get Deleted without Logging in, if it is Theoretically Possible already? 

As far as I know, there is no expiration date of an account, but it wouldn't hurt to check with someone who works for the site.

Here or anywhere?

We don't close them for inactivity

They only close them for sinactivity.

What is sinactivity?

What I have done.

sinactivity would be sinful activity.  eg cheating, trolling, public exposure...  Just an attempt at a play on words.

Thank you for the English lesson  !

LOL 

i like to play naked--will my account be closed?

No, webcams aren't being added to the site

Sould we follow table manners on chess.com, because I like to keep my legs "COWBOY" style on the table...XD
