High post price but low interaction

Now the members start their day on BBS and feel a little good activity. But i saw one thing and it's very disappointing and hurting.

The post price goes to 4.14 with in two minutes and there are nine like on a post but there's only just two comments. It's very shamed for the users who just focus on buying but don't want to interact. They just want to enjoy part from others income but don't ready to support.

We need to give high support to eachothers. And there's few members who are buying now and make the post price so high.

Even i saw a profile of a member she has only 2 CC but she buy a post on 3.18.

How ???
