There is one App blacklisted in Facebook's JS API

And, it's "The Sims Social". Haha. Hardcoded.

{"blacklist":[144959615576466],"sampleRate":500} ... in http://connect.facebook.net/en_US/all.js

Which is: http://facebook.com/144959615576466 aka. https://apps.facebook.com/thesimssocial/

Props to @samvj for finding it. (he's sitting here and I said I'd submit)

It looks like it's just blacklisted (or maybe even just rate-limited?) from something called "CanvasPrefetcherConfig". I haven't the patience right now to read through the whole minified file to figure out what's actually going on, but that sounds more like a workaround for some obscure technical issue than The Sims Social being somehow blacklisted by Facebook, doesn't it?

It looks like it affects a single function, FB.Canvas.Prefetcher._maybeSample, which is:

if (!j.isEnvironment(j.ENVIRONMENTS.CANVAS) || !j.getClientID() || !l) return; if (Math.random() > 1 / l || m == '*' || ~ES5(m, 'indexOf', true, j.getClientID())) return; setTimeout(p, 30000);

where m is the blacklist.

Given that this function does nothing for 30 seconds anyway, it seems almost certain that it's a workaround for a technical issue.

Nice find. I wonder what they were guilty of?
