reserved user account names

With the WHM version 10 (and possibly before) the name test* is reserved by WHM.
When using an automatic account creation application such as WHMAP, if a user wants the domain testertech.com (or anything starting with test) the account will not be created.

I am interested to find out the complete list of reserved names. I have heard there are more than just test*.

I am also interested to hear if this has caused problems for admins and how they deal with it.

I would like to develop a solution that would change the name "on the fly" to something acceptable to WHM, so my accounts will be created automatically without error. I would need to know all the reserved names to do this properly.

Maybe in real life the incidents of this happening are so low that manual account creation is not a problem for most.

 

Thanks for your help!
