This has been a bit of a reoccuring theme this last week, and i think most of the time people are not intentionally using similar names for any devious reason. Lots of people will have the same ideas etc when deciding on a username, and I dont think we can really spend loads of time asking people to change usernames etc. There are already lots of similar usernames and I dont think it would be a good use of anyone times to be checking up on these.

There are special rules on impersonating others and this will be dealt with as per normal.
