Why isn't my Ignore Option working?

[ceres]

Can someone tell me why some posts have an ignore sign in the bottom left hand corner and some only have what appears to be a child's face and some green things? 

You won't see the Ignore button on your own (can't ignore yourself  ;)) or on mods' posts (can't ignore us either  :P).  The 'child's face' is the View Profile button and the 'green things' is the PM button.

The other icons in the bottom left corner are:
= view profile
= visit website if they have one listed in their profile.
= email, not present if they have chosen to hide the address.
= send a private message

Corrected...
Admins/mods don't have an ignore button under their avatar as you are not supposed to ignore them everyone else does however adding admin or mods names to the ignorelist in your profile does work if you want to ignore them (curiosity got the better of me).

Thankyou both.  I don't click on anything until I know what will happen.  Must be more adventurous.
