I've already sent a private message to safar1980.
You're right:
"Connecting to someone else's RPC node allows attackers to spoof transaction data."
But do you think miners don't know that? If I mine this shitcoin, I'll use a new wallet. Even if this project is a scam, the scammers won't get anything but their own shitcoins.

97% of the new projects here are either scams or just made for fun.
Unfortunately, not everyone is aware of the scams and will keep falling for them, so it wouldn't do any harm to put out any warnings regarding them. I mean, we still have people falling for obvious scams such as Ponzi schemes, so I wouldn't be surprised if they could mess up when faced with such scam projects.
