Totally this. Sure, you can set up billing alarms and all, but the point is, for personal hobby projects, it shouldn't be this easy to screw up. I've used AWS extensively professionally at my current and previous 2 or 3 companies, and I've had a personal AWS account but recently decided to close it just to be safe. I actually wondered if I could just remove my billing credit card, so I contacted AWS support about it, and they said you have to have at least one primary card on there. So the only option was to close the account. I only use a mix of Digital Ocean and Netlify and Heroku for personal projects so I might as well shut down my personal AWS account just to be safe, and I did. It's just not worth keeping one open, the risk is too great.
