Ya, sometimes when I make a post I'll see a notification on busy with like 5 new followers within a minute. It's funny because none of them have profile pictures and all the posts are about food, haha. Makes it really easy to tell it's a spam account. Is there some kind of spam account filtering system in steemit? From what I've seen it'd be really easy to have an automated AI system identify most of these accounts. They're not very original, haha.
Yes, I agree that an automated AI system would be perfect. And no, there is no spam account filter except account creation. It costs a bit of Steem to create an account, but Steemit will do it for free if you just provide some information. These bots were probably created by using spammy account information.
If they put more effort into writing the posts, they could make a lot more money!
