Pros
Easy to join little or no qualifications and teaching experience required (can also be a con). Many people have an opportunity to teach. Provides all teaching materials.
Cons
Very poor and confused communication. Responds to only a fraction of messages from teachers asking help to teach better. Answers are often short with little useful information. Very high penalties upon teachers and takes a very high cut from teachings earnings. Took more than half of mine.\ Seems to be quickly becoming greedy for the sake of increasing profits and treating loyal teachers very badly and unfairly to achieve this. Often incompetent and disorganised. Portrays an image of being untrustworthy. Shows signs of racism, ageism and other forms of discrimination towards teachers. Uses a lot of misleading propaganda on Facebook and YouTube. Ignores complaints for teachers with problems.
