No one should need a phone verification to post ANYTHING. NOT EVERYONE has a cellular phone or even can afford one. This is very unjust and hurts small business owners. Not everyone who doesn't have a phone is a 12-year-old with no grasp at social media. (Yes, OfferUp's TOS says you have to be 16+ to use OfferUp.) Homeless people struggling to sell their items often don't have phones. iPods and iPads and such are used as alternatives. Their procedures are classist and ableist.
