I applied and was granted an ESTA a couple of months ago. I am planning to travel from the UK to NYC for a one-week holiday in just over two months. The new ESTA application asks you for your "Online presence," and I gave my Twitter handle and Facebook username.
I now want to delete Facebook: I just kept it to use Messenger on a phone which was stolen last week, and haven't really used it for the past year and a half since I switched to Twitter. I am now locked out of Messenger because for some reason I can't log back in from my new phone. I therefore have no reason to keep using Facebook. I also don't like how Facebook uses your personal information, and I have too many friends who I don't really engage with. Will deleting Facebook now, after receiving an ESTA, cause me any problem with the DHS/CBP?
(Giving out social media handles in your ESTA is optional, but I figured that the US authorities knew I had them anyway.)
