Likely because the IP address is the same right? .aybe even the same machine? It won't let you start another name up from one IP. (one profile per guest stops the troll name change game somewhat) You might try from a device with a different IP (phone, etc) but it may bounce you by listed home address as well; I'm not sure. Once the account is started, I think you can access any one account at a time from any machine.
Otherwise, send an email to them or "report" my reply, that will get some attention if this alone doesn't 😉
They always seem pretty on top of their mail and help posts to me.
