The advantages of the portal:
1. There is no report.
2. Many companies.
3. The payment is more or less on time.
4. Good support in the Telegram.

Disadvantages of the portal:
1. No transparency, can not see the intermediate calculations, are not visible to the participants.
2. Reject participation only at the end of the company.
3. Very high requirements to the written articles. Most are rejected. There are no clear content requirements.
4. Sooo many participants, and therefore meager payments.
