Didn't we all learn the difference of right and wrong in third grade?
We don't always use it.. Let's just use it when it comes to this.
Like, if I see someone post about doing all of the things that I love I will most definitely write them a hello. Just like when someone wants to comment on something that I post without having to have it public they send me a pm.
A, "come see me. You saw Becki and I look like her." seems silly .. Quite honestly that seems like spam. It seems like a message that was copy and paste and sent out in a mass pm. That is spam.
If a lady or a gent sees someone post something and they have something in common that they want to keep private, why not use PMs. That's why we all talk on message boards and have PMs. If the person doesn't reply, oh well.. Like the foo fighters sing, on to the next one. That should go both ways.
