Freelancer.com — Reversal of payment.

I made project in which user upload tokens and generate likes using fb api. The employee said that he/she will be using his token for generating likes using fb api. Project was completed. Payment was done. Feedback received also.
Now freelancer.com reversed the payment and when i asked for reason they were saying that it was bot creation and buying/selling of likes
But when i asked support they provided me with this link
https://www. Freelancer. Ph/faq/onsearch. Php? Keywords=invalid+project

In this link there is nothing like it that bot creation is invalid. They are saying likes selling and buying is invalid but does it count as my project invalid. Please help me with this they are doing this from long time reversal of payment.
So if they can't handle the project before awarding why they are operating this platform. If they can't even recognise the project is suitable with there terms or not they are just reversing payment after the project is completed.

Thanks
