Like most of you, I was suspicious of the come-on attached to "Jen Thomas'" invitation to friendship. Like Jack and Dr. rock, it just didn't feel right. I found her invitation in the wee hours, so I decided to hold off on accepting until I saw if anyone took action later in the day. And Ana most certainly did---and the appropriate one, too. Much obliged, ma'am.
I also received a spam message from "Jen Thomas". It is my understanding that many of the spammers have automated "spider" programs which join social forums likes this one, download the membership list and then start spamming. That is why the various "copy these characters" programs have become so ubiquitous.
