What is spam content?

Hello, can anyone help with what are spam content? It happens a lot that I am not able to post the reply because of it.

Spam meaning posting same content again and again . Advertisement phone number and useless MSG are also spamming

Since ur group is newbie and newbie group can only post 10 post in a day

thanks. I think i had too much of Anu.. changed the same message and added she in most of it and it worked :)
