Do you think most of the users who have him in their trust list don't suggest anything that will be against JollyGood or don't write any constrictive opinion about him because they think they will find themselves in his distrust list? Losing a DT vote with earning a negative vote (JollyGood will put you in his distrust list always) means the users are going to lose 2 voting points. For people who seek DT position, losing 2 points is a lot for them.
I can't say why people do or don't do things, but if you include someone hoping for backscratching, you're doing it for the wrong reasons.
In another thread I was mentioning the users who have him in their trust list, but I am not sure how many of them really noticed it.
I assume most people don't use a notification system, so mentioning them doesn't help.
I did not see many of them (except two I guess) to share their opinions yet.
For what it's worth, 4 people removed JollyGood from their Trust list in the past week:
