I would like to know the moderators' policy on bullying. It seems easy to bully a user. For it takes only 5 users who have sufficient reps to close a question.
Putting a question on hold is not bullying. It is a request from the closers to the question asker to improve the question.
If you feel you are being bullied then this is a very important matter. You have two options:
Come to chat and ping one of the moderators to ask for a private chat so you can disclose the bullying you have experienced, and appropriate action can be taken.
Contact the community moderators with your evidence, so that they can help you deal with the issue.
We do not tolerate bullying.
