do advertisers ever drop publishers?

Lets say you managed to be accepted into a great advertiser's program but haven't done much for them in awhile, do they typically drop you? I've been a part of a few programs that I haven't gotten around to advertising in months, and I was never dropped.

 

I think some of the advertiser may drop you.. so it depends to the advertiser..

 

usually they dont drop u if u dont advertise but if there is any bad activity by publisher they do.
