DT is not a unified front. For example, I care very little about certain things that others have very strong feelings on the matter, such as account selling and ponzi schemes. I'm pretty much of the opinion that as long as you have transparency, no service is wrong, even if its essentially just a can looking or handouts because of  how bad the terms are. (Though begging is against forum rules)

If Lauda cares about buying/selling accounts and they leave you a negative for buying/selling accounts, only people who care about buying/selling accounts will value Lauda's opinion. I however, who typically wouldn't care would disregard the comment, unless there was additional substance that made me care.

If you aren't doing anything shady, don't worry about it. People deal with who they want to deal with. I might have an extreme prejudice against anyone who speaks gaelic, and refuse to trade with anyone who can speak it. My opinion would then only matter to those who share a similar belief. ( I don't by the way, though I suppose I might be a little jealous)
