This card is a problem for rules consistency. In my opinion the rulings on Salsette Slums with NBN: Controlling the Message/Hostile Infrastructure (and I'm assuming Gravedigger/Reaver?) should be made consistent with the rulings with Maw/Aeneas Informant/Aumakua. Either you did trash the card or you didn't. If they really want the interactions to be distinct, at least errata them.

I want to quickly note that this combos with Paige Piper to let you save the other 9 cards from being trashed. And to remove extra copies of the chosen card in your deck if you choose to. This enables playing lots of redundant cards, which helps with the random nature of Frantic Coding.

I can only see this card being particularly effective if played twice in the same turn, perhaps via Archived Memories. However, the conspiracy breakers make it even less effective than it ever has been.

Most commonly combined with Artist Colony to fetch any installable at ability speed (the only limitation is what you can fit in your deck,) Fan Site can also be used with Liberated Chela and an extra click to potentially become actual points, Frame Job for a Bad Publicity, or Data Dealer for straight cash. Those cards also let you dump negative point traps like News Team and Shi.Kyū for a profit, should your opponent offer that opportunity.

Great targets for Artist Colony include Icebreakers, New Angeles City Hall, Plascrete Carapace, Film Critic, R&D Interface, Clot, Security Nexus, Hades Shard, etc.

Do note that this can become a liability with Philotic Entanglement, however.

5 install? 2 to break stuff? 1 strength? An insanely overpriced extra ability? Sounds bad, right?

Well, except for that one line of text: 2: +4 strength. This card is basically Ninja 2.0. Doesn't have to pump for Komainu, takes on Assassin (and most sentries) for 4 instead of 5. Same influence cost. That extra 1 you spend on install is made up for on the first break in almost all cases. (Exceptions being the few 0-strength sentries, essentially just Tour Guide.) It can also be compared to GS Shrike M2, which sees play despite being a Sunny breaker, with Golden pumping better, breaking worse. It even beats Mongoose versus (a few) big sentries (with 4+ strength)!

Basically, its stats are solid. It will see play. (But it has tough competition, from Mongoose on one side and Shrike on the other.)

The derez ability will rarely be relevant. The main exceptions are saving itself from Apocalypse while derezzing Architect, derezzing Janus 1.0/an unadvanced Orion/Archer for a net cost of 13 + click to install, in conjunction with London Library for a free install (there lies jank,) and/or with Nasir Meidan: Cyber Explorer. Costing 11 to install/break/derez doesn't sound so bad when you gain 7 for encountering the Assassin in the first place. They just might refuse to rez it at all. They'll still rez the small stuff, though.
