I honestly dont see why you guys care. If he has two accounts, admin will catch him and ban him. If not, you just look like d**ks for no reason. The only people that care about rep around here are people who are constantly online. So some casual person joining up to find an installer is not going to give two sh*ts about some random dude saying he did a good job.
That said, I guess since things are so slow around here people have nothing better to do.
