1. Hacker_Masters
2. Hacker_Masters
3. "Hacker_Masters"
4. "Hacker_Masters"
5. hacker_masters

We can start with eliminating option 5. Their group name would be a proper noun so it would have to be capitalized¹.

1. Hacker_Masters
2. Hacker_Masters
3. "Hacker_Masters"
4. "Hacker_Masters"
5. hacker_masters

I would then eliminate options 3 and 4. When you use a name of a person or group, you don't need to put them in quotes². It's the same thing for italics² so option 2 is out.

1. Hacker_Masters
2. Hacker_Masters
3. "Hacker_Masters"
4. "Hacker_Masters"
5. hacker_masters

This leaves us with option 1 - the classic.

This would mean in dialogue Hacker_Masters could be called Hacker Masters, or HM for short, and so on depending on your style.

This way you don't have to write out Hacker_Masters with the underscore each time.

Does this solve your problem?
