Do not try to meet someone in the chat!
For chat, the misbehaved person could be pretented to be nice and friendly, but she/he said to you to meet her/him, she/he can do bad things like kidnap you and cause trouble. They can lead you to the bad effected way.
For people, they mostly use animals or pets to kidnaping others, but they can use chat.
Like on chat, for example, User:Gorilla and User:Eagle are talking on the chat, when User:Gorilla says to User:Eagle to meet her/him (Usually use pets or animals), she/he must refuse her/him.
Chat for you, just be a chat. Do not try to meet others in real place.
Especially if that person is a female, you should watch her three times than males.
Reason is I guess the spammers are usually the girls so that's why about the crime, you must watch girls three times than boys.
If you think you are trapped, you have to remember her/his physical apperance or her/his belongings. That could easy way to clue up who did it to you.
So prevent your mess than meet EVEN if you are lonely.
