Something needs to be done about these bot accounts. They will ruin Steem. I get the allure of using them to mine, refer, spam tiny curation upvotes, spam comments, etc. However, it will clog the network and make it even less appealing for newcomers. I hope one day something is done, such as unverified accounts, those not attached to unique phone numbers or which haven't done KYC are discluded from certain activities or promotions in the future.
