This is just one example. I have MANY experiences just like this.
poor quality backlinks especially in bulk will more likely hurt a new website than it will a well established one.
BTW I buy backlinks every day, I pay google to run my ads, and some of those visitors have websites who decide to link to me. I pay an SEO company to create stupid nonsense viral campaigns just so people can talk/link about how stupid and/or funny it was.
I pay writers to write controversial blog posts so people will link to it. So yes, I buy links in many kinds of forms.
