This is a great card for Spark Agency: Worldswide Reach decks! Play out your advertisements as they come, and over time, they may get trashed. Then, use this card to play them all back in at the same time!
The effect on the runner is significant, as they have to spend all those clicks and credits removing them again- and perhaps they suspect you have another copy of this card waiting in the wings! For that reason, I observe that the runner does not generally have the appetite to trash everything a second time round. This then gives you a monster economy, allowing you to get your ice installed and lock them out of your servers.
