Jihadi kenyans

I am not shocked about kenyan girls joining Islamic states(ISIS)... Kenya unlike China dont have cyber investigation..IDK what to call it
You all sitting in living room your child scrolling at her/his phone.. Yes she is in internet you don't know what she is reading... The next day she started wearing expensive jewels buying Iphone 6 etc.
ISIS  have turned to internet for recruitment process.
This goes for weeks then she goes missing the next day she sends you text via Telegram app..just like WhatsApp but hides someone location...like the other gjrls from South C who said they are now in Syria.. The first thing people said and most probably is that they have joined Islamic State.
How can this be stopped?  Internet have advantages and disadvantages
You yes you who are reading what do you use internet for????
