This bug was verified with Chrome Version 79.0.3945.130 64-bit on Windows 10 PC.
Specifically, Spanish language in the Por vs. Para language challenge. It probably works for every language and every browser though.
Replication:
- Go into Spanish, open the Por vs. Para language challenge with 5 multiple choice questions.
- Advance to the final question and get it correct.
- Click again on the green correct answer to collapse the middle part that pops up and asked if you would like to continue or mark it as mastered.
- Left click spam the green answer fast enough so it does not have time to dynamically move out of cursor range as the pop up appears.
- Whenever you decide to exit, your score and level with skyrocket accordingly.
Recommended repercussion for me since I’ve exploited this bug (Twice to verify it): Just reset my score to 0. I think I was like level 4 before I found it anyway.
I hope by reporting this exploit, it will keep naughty folks off the leaderboard. I love retro style of the website! I’ve purchased the subscription, and intend to keep using it. I just stumbled upon the bug and it was not my intent to exploit this to gain leaderboard status or whatever. My intent is to learn. Thanks!
