An anonymous reader shares a report: Twitter is the latest social service to boot out cryptocurrency advertisers. The company told Reuters it will be launching a new policy this week to prohibit the advertising of token sales/initial coin offerings (ICOs), and crypto wallet services. Ads for cryptocurrency exchanges will also be banned -- with some limited exceptions. Facebook announced a ban in January, while Google said earlier this month that it will ban them from June. In a statement, the company said, "We are committed to ensuring the safety of the Twitter community. As such, we have added a new policy for Twitter Ads relating to cryptocurrency. Under this new policy, the advertisement of Initial Coin Offerings (ICOs) and token sales will be prohibited globally."
