i was with a gentleman the other day . when we got talking about phone numbers . . . for example if you put your no into google what comes up. i did it and
for me it was a conversation i has with a person on here , i have cleared my phone at all times of these chats and the link from my number led straight to my profile on here, that's damn scary . im not the only one that has my no . as i tried loads of other numbers and nothing happened with them .i guess I'm just lucky. how can i stop this . please any ideas would be gladly accepted . i am changing my number , but was wondering if it has happened to anyone else? and how can i deleate some messages in my profile as there is no deleate button only a report one?
Help anyone?
