I am making a big fuss over this because it annoys me, that people can't think of original names; so they have to copy other people, because they are popular.
Often you will find, or may well have seen, these 'fakes' have posted Instructables, but the original person has posted a gun, more than five times better than that of said cheat.
The few I have found so far include:
Trainman2001 - DarthTrainman
Dsman1 - Dsman195276 (or visa versa)
Killerk2, NOT-KILLERK - KILLERK
There are thousands for ironman69, although there was a film called The iron man - This could be a valid reason.
If you spot any other clones, inform me please.
I will eat them.
