I can honestly say I've been using varagesale for about 7 years, you just need ONE PHOTO & your name (or any name) to get approved & the rules are not that bad to follow
Examples (No counterfeit items. No animals allowed, always follow the time when you want to sell or buy an item 'if you sell or buy an item make sure you contact the first person who messaged')
I've had problems with it sure, people were mean/racist to me but I told the administration & they revoked there account.
Also you CAN CHANGE YOUR NAME. My name on the app isn't even my real name.
