None. I hate pass-aggro; I’d rather be dry (bald-on record) or upfront (plain aggro).

What I’d do in this case depends mostly on

1. if I trust some person in power to handle this shit in a smart way. Either one in charge of the group or the school.
2. how insistent the NFT scammer is.
3. how much I care about other people in the group that might fall for the NFT scam.

For #2 and #3, on best hypothesis (no insistence + I don’t care about others) I’d simply answer “not interested”. However, get me motivated enough and I’ll be rather colourful with language usage, to the best that the platform allows me. Such as:

As I already bloody said over and over and over and over, I do not want your NFT bullshit. “No” means “no” for anyone with basic reading comprehension, unlike you. Your NFTs have zero intrinsic value. You might be able to convince some goddamn morons to join your pyramid scheme, but I’m not doing it. Is this clear??? Stop insisting and fuck off.

Further links for anyone interested: [link associating NFT bullshit to pyramid schemes], [Wikipedia link explaining pyramid schemes] I heavily recommend you guys to read this before buying anything from this guy.

Followed by blocking the moron for the sake of my own sanity.
