Got text alerts about possible sexting

I just installed some software that alerts me when dangers are lurking around my 16 year old daughter. Sexting is an awful problem and I got an text alert that was picked out words in an Facebook post that said "photo of me". The software then showed me that it was someone who had tagged a photo of her in Facebook. What a relief to see that but also very reassuring that I can now monitor activity and keep abreast of any potential dangers. I would rather be alerted more times than not be alerted at all. I wouldn't think that my daughter would be involved in sexting a picture of her but you don't know who would send one to her. One of the beauties of the software, it would then allow me to block those who would send such awful stuff to her.
