Non learning related messages - what do you do?

6 years ago

What do you do when you receive a message that is not related to learning or teaching?

I don't like being rude to people.. but why would someone waste my and their time?
I received three in one day and two of them looks like same person with a different name.  They are all English native speakers, so why contact me?
I am not interested in sharing my personal numbers with anyone. 

I teach school aged children and thought that with Verbling I would have communication with adults.  Looks like children are much better option.
