It seems likely. Two new users, "lamamma" and "lamamma1" registered consecutively today, using two similarly-named Hotmail accounts. Evidently something didn't work with the first Hotmail account, used to register "Lamamma," so he/she created a new Hotmail account and was registered "Lamamma1."
It also appears (from resolving IP addresses) that this "new" user hails from the same region as Adoptive Dad, and it's likely that it's either our old friend using another computer, or someone doing him/her a favor.
Sadly, we may need to switch to a registered-user only format, with administrator review required before new users' accounts become active. I'm reluctant to do so, but it may be necessary to protect the civil, respectful community that the Abrazo Forum has been for four years now. We'll wait to see whether this nonsense continues.
