Comparing is probably not the best method one should use for determining how to file this income because it is so dependent on particular circumstances. Some people do use vine like a business, resell items they've received, spend a significant amount of time engaged in the activity, etc. Others do it infrequently and don't sell anything they receive. I personally am filing as a hobby and if they want a statement why I chose that, I have a document prepared to defend my reasoning
