Definitely not. In a light novel or in real life, blackmail is a serious wrongdoing that can lead to severe consequences. It's not a behavior that should be encouraged or depicted positively.
You can't. Blackmail is a bad thing and goes against moral and legal principles. Light novels usually focus on positive and interesting storylines, not such negative actions.
Since I don't have detailed knowledge of this specific light novel, we can make some educated guesses based on the title. 'May I Blackmail You' gives the impression that there is a certain amount of permission - seeking in the act of blackmail, which is quite an interesting concept. It could be that the blackmailer has some sort of relationship with the victim that makes them feel the need to ask in a strange way. Maybe it's a case of a love - hate relationship where the blackmail is a form of getting the other person's attention or forcing them into a situation. The story might then revolve around how the victim reacts, whether they give in to the blackmail, fight back, or try to turn the tables on the blackmailer. There could be a lot of twists and turns as the two characters play this dangerous game, and it could also involve other characters in their social circle who are affected by their actions.
Some popular platforms for light novels include NovelUpdates. It often has information about where to find various light novels, including whether they are available on official translation platforms or fan - translated sites. Another option could be Amazon Kindle, which has a growing collection of light novels in different languages.

I once heard about a teacher blackmail story. A teacher found out that a student had cheated on an exam. Instead of following the proper school procedures, the teacher threatened to expose the student publicly and tell their parents, unless the student did all of the teacher's personal errands for a whole month. The student was terrified and initially complied, but finally gathered the courage to report the teacher to the school principal.
One blackmail story is about a businessman who had some unethical business practices. An employee found out and threatened to expose him to the media and authorities if he didn't pay a large sum of money. The businessman was in a tough spot as his reputation was at stake.
One way is to communicate clearly. For example, sit down with the family member who is blackmailing and firmly state your boundaries. Say something like 'I won't tolerate this behavior' in a calm but assertive way.
