Why do my comments on the posts in the community board show as pending?

Hello Sona. There will be something within the posts that the automated 'bots checking don't like. 

There are certain words that trigger it. Cut 'n' pastes seem to do it sometimes. As do links sometimes.

Generally, assuming there is actually nothing that breaches the message board terms, they are cleared fairly quickly. 

You can have a bit of a play around yourself and remove or change some words that you think are suspect to see if that clears it instantly. 

Thank you. Your explanation helps alot
