Are they alts? or it just an innocent mistake? 
I have been there 
I created a thread in 2021 about a similar situation but it was not a football club, it was a football players:
Several Accounts Misspelling Manchester City Footballer "Kelvin De Bruyne"
I was gonna lock this thread if there are 20 users used "Real Midred", since it's still 3 users, I will leave this thread open...
I am glad you kept it open, do not lock the thread. This matter should be looked at in greater detail because the accounts you refer to are not exactly quality posters. If there are three members that predominantly misspell it could easily be overlooked but if any of them have engaged in dubious conduct and/or have unfavourable (neutral or negative) tags then the chances are there is something untoward going on.
