I think 'dash s' meant '/s', i.e. sarcastically bold.

This comment shows how unnecessary the /s is. Even if you write it people will take it seriously.

Additionally, it destroys the irony for the readers who understand the /s.

They didn't write '/s' though, which is why I mentioned it - took me a minute to understand 'dash s' so thought the commenter I replied to might not have.

(Perhaps '/' is called a 'dash' or something similar in other languages, but it's an 'oblique' or 'slash' usually in English. To lend weight to that theory, I believe 'oblique' comes from it being the oblique/italic form of a dash - so other Romance languages may well give it the same or very similar name to that for '–'.)

TBH, I understood it was sarcasm. I thought it was funny to note the combination of "NFT" and "no scam" anyway.

As is including “no confusion”
