If they’re creeping you out, the best option is to stop talking to them. I know that social conditioning says to just not say anything, and be nice and let them talk, but when they’re sending you videos like that right off the bat?
Run, and don’t look back.
If he keeps messaging you, don’t worry about appearing to be mean, block him. Your safety is more important than toeing the social line. Please, please, watch out for yourself before worrying about whether or not you seem mean to someone who is creeping you out.
Also, his asking you your age that quickly sends up red flags to me, when combined with the rest of it.
And anyone who’s following me – if someone is creeping you out when you talk to them, either in person or online, listen to that feeling. Don’t tell yourself that you shouldn’t be mean, or you should be polite and keep talking to them because maybe they’re just awkward. Watch out for yourself, and do what you need to do to get away from that person.
If you’re online, block them. If you’re in brick-space, have a signal you can send a friend or reliable relative or a responsible adult you trust. If they’re supposed to be a date, make sure someone – or multiple someones – you trust have pictures of you that day, have a picture of the person you’re meeting, know where you’re supposed to be going, and when you’re planning to be home.
Be safe. Trust your instincts. Watch out for yourself and each other.
