Is it wrong to not want someone taking care of a family member because of the contents on their Facebook?

My sister is severely disabled and needs someone to constantly watch her due to her seizures and her regressing health.
She recently got a new aide, and I came across her Facebook.
Her pictures are either very provocative or are her flashing the middle fingers at the camera.
Her typing is in all caps, “text speak” and every other word is a curse word.
She describes herself as “EXOTIC, HUSTLA, DAT BOTTOM TYPE CHIC YA DIg??”

Is it wrong that I don’t want her to be the one that takes care of my sister because of this?
