Did you ever notice that there are so many scammers and persons who try sell you something? They have the same approach, same style, phrases etc: pretty girl avatar, "where are you from? I'm Nancy, Kelly from.."
They are so annoying and I thought everybody aware about it. Were you ever approached by scammers?
It's been a long time that there are a lot of scammers in that platform.
Just block and report them if you keep receiving messages from them. Use that feature to avoid them and they won't be able to message you again if you're active in a channel.
