# Comments type

How do we determine the type of comments? We use machine learning and our special lists.

### Which are the author’s comments?

Any comments left by the account owner.

### Which are real comments?

Any comments which do not contain words related to selling services, goods, suspicious offers, and, rather than only emojis, contain text as well.

### Which are short comments?

Comments that contain no more than 4 words. Emojis do not count as words:) 

### Which are suspicious comments?

Any comments that contain offers related to selling goods, services, tags (@) and words that we regularly update with machine learning dictionaries.
