Also a dog that they sent to a bad foster who ended up with a bite due to their own stupidity.
There's only so much a rescue can do to control the behavior of its fosters. Unfortunately everybody is so hard up for fosters all the time that almost every rescue will gamble on an iffy foster home if it's not obviously super terrible.
And most fosters are just well-meaning regular people who don't necessarily have a ton of expertise in handling dogs of any sort, let alone dogs with behavioral issues.
I'm not taking a stance with regard to MAGSR one way or the other -- I've never dealt with them personally and have, at best, third-hand reputation-type information that's pretty much neutral and therefore not too helpful -- I'm just saying that it's not always fair to impute the stupidity of one foster home to the whole entire rescue.
To the OP: you'll find that most of the good rescues have pretty extensive applications. Shelters tend to be a little simpler because they're usually dealing with higher volumes in a less personal setting.
But when you adopt from a foster-based rescue, you're taking a dog that's been living in somebody's home for a while, almost like one of their own pets, so the foster always wants to feel comfortable that the dog is really truly going to a great home.
And a foster-based rescue really wants to make a good match. That's the biggest benefit of adopting from a rescue rather than a shelter in the first place -- you can get a lot more insight into the dog's personality, activity level, behavioral quirks in a home setting, and so forth. But all this extra information can't be used to maximum advantage if they don't know enough about you
to figure out which of their dogs would be good matches. So that's the other main reason they typically ask so much stuff.
Not that you asked for an explanation. I just talk too much sometimes.
