Set some username rules regarding similarities?
 

Hi there,

Does anyone know of any code or mod that disallow usernames that are TOO similar?

e.g.

Ice Cream Lover
icecreamlover

?

Nope, I've never seen anything like that. I imagine it wouldn't be that easy to write.

I found something to disallow spaces...

that should help quite a lot.

Thank you very much though for your prompt response!

I would very much want something like this. Nor only for spaces etc., but also for similarities.

What would you define as 'similar'?

F.ex: If a user is "Johnathan" then a "warning" should be given for a new user trying to register as "Johnattthan" or "Jonathan".

There are so many variations, and so many user names to began with, I don't see this as something that is possible.

But looking for, say, 4 identical subsequent letters?

I have never experimented with it, but in MySQL you have something called SOUNDEX what might be usefull in this case.

I have no experience regarding codes, so that would be far off my level to try making this on my own. ;)
