> New unverified accounts to 300/day This rate limit may stop the most extreme scrapers, but it won't come close to stopping moderately large operations. AFAIK nothing is stopping you from creating as many accounts as you want, each of them associated to either an email address or a phone number. Even if they made it more strict and required both a phone number and an email address, it would still be a trivial process. They will give up in the near future and implement some annoying Amazon style captcha, which scrapers will again circumvent with rotating proxies and captcha solvers :-)
