Not if you value your email address, that is. I’ve signed quite a few of them on prompting from Sista, but recently I’ve started received spam on the unique email address I set up to subscribe. I reported it to Avaaz and received an assurance that they don’t sell or share their list, but that they’ve received reports and are investigating. I asked them to follow up, they didn’t. Obviously their security has been breached.
