Unfortunately this is sad true. But if you worry about bounties, twitter ban only advertisement like banners and so on. But also I've heard about a lot of twitter accounts promoting ICO to be banned,so be careful
I think spam accounts only will be banned so bounty participants need to have time limit while tweets or retweets and still there is ni confirmed status about what they are going to ban because recently we heard that facebook banned ICO advertisement but now they are going to launch their own crypto.So we need to wsit and see waht about twitter and others.
