OfferUp complaint: Removal of a prohibited item

I put a multi chamber water pipe on offerup. I looked up smoking pipes before I did it and there are a few on the app that have been on for over 2 months. The jerks at offerup said I have a prohibited item for sale and removed the post. I want to know how these other people can sell the same type item for over 2 months haven’t been removed and it’s only ME? I feel I am being disrespected, discriminated against and forced to lose a sale that they have promoted several people and allowed to make sales for the same thing, a smoking pipe. I did not mention the use of any type drug, only it makes it less harsh on the lungs when you use it. That is truth and does not promote drug use. These people are hypocrites. Go to offerup app, type in smoking pipes. You will find many, not 1 but many, smoking pipes, hookahs and such that don’t mention drugs and arehave been allowed to sell for months. Makes me very angry. -5 star review on a company that is prejudiced for some reason.
