When you get a red tag by DT members, it literally mean your account already destroyed since many users will think you're a scammer, bad person, etc etc that would make you not cool in this forum. It's very important even though you're not participating a signature campaign, but it will damage your reputation and if you have a services, anyone will think twice before hiring you.

Of course a negative feedback wouldn't stop anyone to contribute in this forum, but it's very important for the other things that need a reputation score.
