Olx — Account banned without any reason

Website:

www.olx.com

I am using olx for more than 5 years. In my usage, I was looking for a phone for my brother. I saw an ad of relame 6 pro which was selling for 12000. I asked in chat for price. He send a photo containing number "[protected] with writen call me". I called him and he said he is talking from Delhi. I know now, it is fraud as he said he will courier phone. I cut the phone and opened olx, so that I can report him. But it said " your account has been suspended".
I have reported more than 100 fraud ads in olx. Then, why my account gets banned. My email id is " [protected]@gmail.com".
