I like to think of myself as an inverted paranoid, in that I am an extrovert who tries to see the good in people before I look for the bad. I've also been a practicing AB for nearly 40 years, and I've come to the conclusion that being an inverted paranoid and an infantilist is often fraught with peril.
I've had 20 babysitters since 1985, but only two were professionals. Actually, of the two, only one was a 'real' pro. The other was a 'pro wannabe' and I was her first AB. All the rest I found myself, and they and the one unskilled 'pro' all came to my house to care for me rather than me going to them.
In the main, I think Moo is right: 'Mommy' types are far more likely to be scammers than to be the real thing. However, this has been true ever since the 'Mrs. Davis babysits' era in the mid-1980s. I guess that's why I've been content to find my own babysitters, and I've always been able to find women who were willing to care for a big baby. Some became quite good at it!
The scammers are banking on our desire to keep the 'baby' side of our lives hidden. If you're ready to look in the mirror and say, "This is who I am, and there's nothing wrong with it," then you're ready to take the steps necessary to reclaim the money these folks stole from you. If you aren't, on the other hand, the job becomes substantially more difficult
