If i choose that, i post his trades link (spam trade), i will get ban?

I saw a guy trade that have 3 same items that he want to trade. 2 trades have the same things that he want / the item he want to trade. The other 1 have the same 'left thingy' and different 'right thingy' but the same item that he want to trade. If i report and put 'other reason'... i can get ban??
