While it may not be a scam in your opinion, it could be considered spam. Spam is not appreciated by the community and could be flagged or may result in action from the cheetah bot..
Some things that can be considered spam:
- Banner ads of any kind
- Referral links/codes
- Repeating the same post
- Links to known scams, phishing sites, and other dangerous links
Actually the ones who spam here the most on steemit are all these bots spamming peoples post with comments! Theres gonna come the time where they're gonna have to do something about this & weed all these bots off of steemit!
