It just depends on how crafty and smart you are with signing back up. Although the old you is banned for life, create a new you and don't have anything the same from your first account. I can't tell you how many times I've been "banned" from a ppc platform only to get back in the same day. One time an advertising platform knew I was making so many accounts and they couldn't stop each one, they actually changed my campaign's names from something like "Ad 1" to "we know who you are" and "we're going to catch you" etc... They knew all my contact details were fake so contacting or finding me wouldn't do shit. Their only real way to contact me was to change my campaign names and hope I noticed. I did notice...but didn't care as I had them by the balls.
