Or, do people actually fall for this stuff?
I give you sumcoin:

A coin that has no free wallet. You have to buy it on Google Play / iTunes
https://slicewallet.org/

Incorrect info you're spreading.   The wallets are free and anyone can look at your link to see the same

You have to fill out a google form to apply to mine on their pool:

Also incorrect.   Here is a site that shows available pools https://pools.show/coin/SUM

They actually threaten to sue people who mine it elsewhere or even discuss it:

This site was attempting to promote the testnet chain and create misinformation.  Seeing you stand up for that causes doubt about what you stand for here.  You changed the context by leaving it out entirely.
