If you are a new member, especially if you have 0 posts in your name, this is how you safeguard your profile from deletion:

Customize your profile in a human way, complete your profile
Post a hello message here before anything else.
Refrain from post with no content, like great idea or thanks so much -- rather use the thanks button
Give thanks if you read stuff that's useful: it increases the evaluation of the thread
Be human: humor, irony, self-relativism and vulnerability are the key...
