Look here people , I am annoyed but I am saying this as nicely as possible
So sorry of it is rude .
Advertising in the library is certainly annoying me and other people. Not those advertisers who recommend to read other people'a books. No that is really kind .
But this advertising . " plz join my group ". It is really annoying . You just write please join and send the link and all. Now come one. You can post this on your wall also . Even in groups if you like. But why write in the library. I am not saying this is useless but it is a bit annoying. Please post all this on you wall.

If I am rude , I am sorry. But please stop !
