Yea sexual offenders especially lie, that is part of the grooming process and luring you in.
Sure most people are safe, but its the offenders who you want to avoid; and unfortunately the internet is a means of luring trusting people like yourself in. There are lots of ways to meet people without putting yourself at risk. Once you've been assaulted, you can never erase it from your life and it leaves shocking scars and forever lasting damage. You can dramatically reduce the chances of being attacked by making wise choices.
I hope you never ever ever go to a person's home without knowing them significantly via fact to face meetings first, in public.
