If you find a bug on the bounty campaign will you use it to gain more coins or email the brand?
Also, it is not said by the brand that rewards will be given for finding the bug. Will they still give reward if you email them about the bug?
Is that word bug referring mistakes?
If you find any you need to report it on the thread or PM it to the manager but I don't think you will get extra reward for doing this unless they have some campaign under that category.
