A bunch of people are worried that Twitter will suspend accounts due to paid promotions related to cryptocurrencies. It seems a bit like unnecessary worry. First of all, that policy has been updated for a long time. Who has seen accounts actually get suspended? Secondly, Twitter is about to launch its own crypto wallet and payment features, so it's unlikely they'll impose very strict restrictions on individual accounts. Of course, those scammers promoting scam projects/exchanges every day, they definitely deserve to be banned.
