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
These links are quite legit. I use them every day. I just wish that someone had shared them with me before I got in. If they are against the rules, I apologized.
