Monique's comment seems helpful. "it's been prevented to release a bad review from the employer by removing his project. I suppose it is better now. at least he is not able to release a bad review on my profile." *I prevented receiving a bad review from an employer by removing his project. Now, my reviews will look better, because he is not able to write a poor review on my profile. Or "When I found out I was about to receive a poor review from an employer, I had his project removed from my profile page. Now, at least he won't be able to write a poor review." [Personally, I find this unethical.]

Hello. here is a correct sentence: I was able to prevent a bad review from my employer on my profile by removing his project. I suppose it is better now, at least he is not able to write a bad review on my profile.
