One of the biggest reasons a person may want to quit hopscotch is because they do not get likes or follows. Everyone can be "Hopscotch famous", it you put effort in. A lot of people get criticized for this reason for leaving.
Another reason is because some people aren't as kind as they should be.
Some hopscotchers assume something bad about other hopscotchers and point that out. That's very bad and embarrassing for both people. Luckily, the hopscotch team and other hopscotchers are trying to stop this.
Next, is attention. This applys to being , mean and publicly saying you are leaving because of likes and follows. A handful of hopscotchers said that they would hurt themselves and really haven't. This is very bad and those hopscotchers have been off of hopscotch ever since.
Another one is remixing. Remixing means that you can make a project even better and publishing it. Credit is always given in a remixed project. Although, some hopscotchers just remix projects and say that they have made it. This led to very mad hopscotchers.
Then there's hopscotchers saying that they don't know how to code. They give tutorials in the app and you can ask for help in the forum. It's okay to stick to the basics. Some hopscotchers have added really easy codes to the basics and have been on featured and trending.
This last reason isn't bad at all and anybody who quits for this reason should never be criticized. This reason is quitting because you want to go farther than hopscotch and start learning and typing other coding languages.
