MPGH = Multiplayer Game Hacking
Nowhere in the title of the website does it mention anything related to bragging.
The purpose of the website is not focused on that either. You would be better off "bragging" elsewhere like social networks.
Having said that, people in the general section tend to already post certain achievements they have made in regards to whatever it is.
If you do want to brag, there is a special section for those posts that we call Spammers Corner which is a subsection under the general section.
