epvp is a good way to infect people with viruses, and self made viruses are not recognized by an antivirus as you just create it :o Releasing tools which track users who use it, require admin rights, can do anythings, stupid players will not be careful about that.
People want every program that might help them, call a program "SuperTool" and make a good interface that show an error no matter what the user has done xD (and they will obviously complain about your program not working, here you can ask the user to open your program with admin right.) Also a good fake picture showing what your program look like if it would work, encouraging people to take it.
Community is stupid, enjoy it :D
