It's a complicated topic, but it's true. I actually mentioned that in my post about downvotes. This type of downvotes or zero lists can prevent users, whether good or bad, from receiving a few dollars or even cents, but it has caused those users to sell thousands of dollars worth of HIVE, and if they were considering buying in the future, they will never do it now.

And sure, there are users that spam, scam, and don't bring any value at all, and they well deserve to be on those lists. Who determines that? That is why it can be complicated. Some users have committed abuse, either by mistake or on purpose, and many times, they are put on those lists without a second chance, and many times, they give up. It's very hard to onboard a user, and very easy to scare him away.
