You can't. You have played games with other players and those belong to them too (and of course the site). So, those will always be there.

I have cancer. Couldn't believe to diagnose...I wasn't carefull with the signs of the disease.
I'd like to delete all my internet activity in the next few months.

That's as good as it gets.

Your the 5th person this week that's caught cancer from this site What is Eric putting in the water?

Actually, your ahead of the game because....trust me....nobody is "careful with the signs". If you were just diagnosed recently, there's 5 stages. I don't mean "of cancer". I mean, anger,denial, grief, acceptance....??
There's gotta be some cancer support groups on-line. If you don't have a pet, GET ONE! Even if its just goldfish. Its not the end. Its the Beginning.
Do you really think we're gonna let you off the hook that easy? Your stuck with us, and we're stuck with you so lets make the best of it. If you can, read the book; "To Heaven & Back" by Mary C Neal. I'm not pushing religion. The author is a SURGEON!

You could post porn. That'd be a quick way to get your account deleted.
Would only get the account banned. Games would still be around and some other stuff.

There's no way to get games deleted. I guess the TC's just going to have to live with that.
Not yust closing account so you can come back. Delete forever!
