It will be very hard to know the intention of everyone creating a similar username account on this forum, so let us not just debate on what we may not have a definite solution to, everyone is free to make use of the username he desires as long as it does not be taken, there might be similarities from from this names, but once they are not the same, then we may judge it to be on a neutral intention not to impersonate or perform an in illegal activities with such.
Did you see the kind of username that Op called out? - officialmoderator. This is not a coincidence and no one with good intention will create such a username.
Similar type of usernames that should attract a permanent ban are;
- ForumStaff
- StaffMember
- OfficialStaff
- MeritSource
As harmless as Meritsource might look, someone could pull a scam with it by telling newbies to pay a certain amount for an x number of merits.
I agree with this, if the name is trying to impersonate someone working for the forum, like mods, staff, admins, etc. Apart from that, if the name is trying to impersonate someone else, I think the forum community should be the one to handle it, giving the account red tags should be enough.
I agree, the forum might not protect all the reputable users, but the community has the responsibility of responding to such types of impersonation.
