https://mapcomplete.org is an easy-to-use website to view, edit and add points (such as shops, restaurants and others)
https://learnosm.org/en/ has a lot of information for beginners too.
I've never had a problem with magic earth, personally. They have a feature that allows users to report road closures, speed cameras, etc... What may be happening is that a user local to your area is falsely reporting things for one reason or another. Unfortunately, I'm not sure there is a whole lot to do about this. It might be worth contacting the company about it.
The user reported events don't directly affect routing AFAIK.
I share your experience though, no problems for me yet. Their FAQ ~~heavily~~ mentions that you should contact them in case any of the data is wrong.
