Alkaline water. Unless you're in kidney failure or DKA you don't need to change your Ph, and EMTs and ER docs aren't ordering supplies from Phountain.Even if you could change the Ph of your own blood by drinking water, doing so would probably kill you. -u/Stoutyeoman

Hydrogen-rich water. Had someone I know (this person is also into MLMs) try to sell me a thousands of dollars water filter. I looked up if there were any legit studies done on the health claims, and as I suspected, I didn't find any really compelling science. Turns out most of the claims pretty much line up with the health benefits of just drinking more water in general. -u/nerdypursuits

Pretty much all Youtube ads these days. If it starts with "this one trick can" or anything like "doctors hate this" doctors hate it because they have to explain green tea doesn't cure type one diabetes. Tbh, it's flat-out dangerous false advertising but youtube doesn't care. -u/neoben00

Kids iPhone/iPad games. My kid is downloading these “free” games that constantly ask her to buy an extra skin or a treasure box of thousands of coins to upgrade and keep playing. It’s really scummy because they know exactly who their audience is, children who have no concept of money. -u/0wlBear916

Online dating services with monthly subscriptions. Any business that gets more money by failing than succeeding will be designed to fail, succeeding just enough to make users feel as though they can succeed. Basically the same principle as casinos. -u/IndigoFenix

Filling your tires with nitrogen for an extra fee.The air we breathe is over 3/4 nitrogen and added that extra 22% nitrogen to your tires will add no benefits and cost you anywhere from $70 to as much as $179.Unless they are doing it for free, you are being sold snake oil. -u/That_Is_My_Band_Name

The IRS will not call you to settle debts. -u/Revlis-TK421

The credit score system.How it should work: pay back loans early/on time, higher score. Don't pay back loans or pay back late, lower score. How it actually works: Pay back a loan too quick, score goes down. Open an account, score goes down. CLOSE an account, score goes down. You even ask for a copy of your credit report, your score goes down. It's ridiculous.It's not about your reliability, it's about how profitable you are to creditors looking to milk interest payments as long as possible. -u/MoochtheMushroom

Work 110% at your job and you will be successful.Yeah you'll be successful alright doing the work of 3 people while the people who don't work as hard get promoted because you are too valuable in your position. -u/NoSpray2890
