I’d wager VWP visitors outnumber Visa applicants by a wide margin. Assuming they actually intend to perform even a cursory check of each social media account they’ll get bogged down for hours by trying to prove someone lying about not having a certain account.
As an aside: someone posted a screenshot of the form showing one of the named sites was MySpace but doesn’t include Telegram (and you can use Telegram without a username too). Anyway - I hope someone comes to their senses (perhaps an ACLU lawsuit re: should people be forced to disclose membership of sites like Grindr?) and they remove the stupid question.
My guess (pure speculation) is that they won't manually check most social media accounts indicated on the form, but will automatically check the provided info against (and add the provided info to) some intelligence community database. Then they'd manually check any cases where security concerns are flagged by that database or otherwise.
