Your app gives Facebook bad publicity. That's pretty much the gist of it.

See Breakup Notifier[1] and Girls Around Me[2] for services that did nothing else but highlight what the platform allowed people to do.

Breakup Notifier (later Crush Notifier) later managed to get on Facebook again, so if (when) you get shut down, try contacting the guys behind the service to see what they did. There are a couple of HN submissions about them.

I call BS. There is a snowball's chance in hell Facebook have seen this, let alone approved it. One of the options is to defriend everybody. How is this not a malicious action?

That option is a joke and isn't an actual option. If you click it we give you an alert: "you can't actually be that mean."

The other options allow you to post content on someone else's behalf, without their consent. That is unauthorised access, and probably against their ToS. I would be extremely surprised, and concerned, if it was not.

Your footer is just hilarious of course. You claim that you do condone unauthorised access to other people's Facebook accounts, on a site who's only function is to let you make unauthorised access to someone else's Facebook account.

Agreed. How is this any different than taking over a friends email account or cell phone and deleting data or sending malicious messages? There is nothing interesting or clever about this.

"Did a friend leave Facebook open? Mess with it now" sure sounds like encouraging unauthorized access to me, tiny "in no way encourages" message notwithstanding. If it actually removes all friends like the button says it does, that's definitely malicious.

Further, the "We only use the word Hack in our name to concisely disclaim the site's ability to mess with one's facebook account." makes very little sense at all. Did you mean proclaim instead of disclaim?

If it doesn't encourage, it certainly enables. The whole point of the site is to let you exploit unauthorised access to somebody else's Facebook account. The footer is a non sequitur.

Hey guys - I'm one of the FB engineers at Penn. This app has a great looking design but definitely goes against the spirit of the platform as well as our TOS.

With that said, next time please seek us out at the hack (I have a hard time believing anyone OK'd this) and we can work with you to ensure that your app can be funny but still benefit users in a meaningful way.

Clarification: FB representatives here only ok'ed the use of our flavors concept, not the spirit of our app.

While setting a facebook flavor alone isn't against the Facebook TOS, we realize that directly encouraging people to jump on their friends' Facebooks is clearly against the spirit of the platform.

Remove all friends sounds malicious to me. Must say that I haven't tried the app myself.

That button doesn't actually do that. It's a joke we added in.

From as many times as I've seen you have to explain it, I don't think anyone is getting the 'joke'. May be better to remove it and avoid the jabs.

For sure...we removed it right after we got the feedback from HN.
