Ciprian, if you will tell us more about the job, we can help you troubleshoot it right here. We like talking about these things.
I have personally had some jobs I posted get removed by automated algorithms, and I was able to adjust the wording so I could successfully post them and hire freelancers.
I checked your account, and I saw that the team has already reached out to you via a support ticket. Please refer to the information they shared on the ticket. Please let us know if you have any questions. Thank you!
