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
The only thing I've done in that list is to post a referral code, which I included a disclaimer for. I didn't know this was frowned upon.
I've been using this site legitimately to collect small amounts of cryptocurrency, so I think it's unfair to see this post as not being useful information– but I accept your criticism.
