I just think the add doesn't fit into the board... it's too prominent when blinking and animated.... besides my sense of esthetics I have no problems with it. 
 
I don't believe people will think of it as something the poster has control over when it appears in all posts. 
 
I would have concerns being related to it if there were like 3 or more adds randomly displayed.
