Prevent specific sub-strings in usernames

[WebCMS]

In vBulletin, there is an option to add to config.php to prevent users from registering with misleading usernames like "Moderator3", etc. Is there a way to prevent substrings like "admin" and "mod" in usernames? This is for IC Cloud hosting account.

You can ban specific IPs, emails, and names in the ACP. Check this guide for more details: https://invisioncommunity.com/4guides/staff-and-moderation/warnings-restrictions-r84/#banning

 

The example in the guide uses the admin substring you mentioned. 👍

Thanks! So does this actually disallow the user to register using reserved substrings or does it ban the user from registering altogether even if he retries using a valid username?

Also, do you see a Ban Setting like this in your installation?

Not sure if this Ban Setting came as a default and if it is necessary to keep it. I don't remember adding such an entry before.

It prevents registration with those users. They could then try another username should they wish to do so.

That entry you show is not a default entry, no
