Our circle is just like the entertainment industry, full of gossip! Contract commissions are risky business, so I have never done any exchange commissions to date. Of course, doing commissions for large exchanges is not a big issue; it's a mutually beneficial arrangement where users can save on transaction fees, and those doing the commissions can earn a bit. It's a win-win! However, to indirectly lure others into trading contracts for the sake of commissions, akin to eating blood buns, is truly unethical. Assuming you engage in such behavior, and I want to take you down, you will definitely experience some consequences. Please remain kind in life.
