Firstly, it’s a bit suspicious that your name is only a few minutes old. Secondly, I hope you live in a society that understands innocent before proven guilty, because all you’re doing is insinuating to damage someone’s reputation.
You haven’t proven anything, that last name coincidence is nothing. These are different last names. You’re damaging an individual’s reputation without any substantial evidence.
As somehow who lost a close one to cancer, quit now and not later. The more you wait, the greater the chances you’ll get cancer. Don’t wait and regret it.
