I might be doing something bad?

I put up an add up today.And their's a blue eye dot on my add? it says (thread watched)? im the only one with the dot? OO?
It is fine. It is showing that you are watching the thread. You can “watch” threads you want to keep track of in a list. Mine defaults to making any thread I create a watched thread also.

Then you can go to the menu and click on watched threads to show you a list of what you are watching.
