may I ask a question? can people introduce their NFT projects here in bitcoin forum with leaving the links to their website and social media? I thought it was against the rules. i don't know. maybe I misunderstood the rules.
Yes, you can do that. There's nothing preventing you from doing so. Just make sure to read the sticky topics to understand the rules better (don't spam, don't promote something illegal, etc.) other than that, you should be fine.
