Well, perhaps I don't use your name; Maybe someone else does, and I use some other's name... In reality, without Facebook's Help, how would they verify that the IP addresses posting as Susan Someone really belongs to Susan, and not Jane?
Are you suggesting that they just took the names and added them to the no-fly list without identity verification? Is this not even more outrageous?
Well seeing as the people with those names actually did try to go to Israel to protest, yes, I'd say the people were stupid enough to use their own names in public groups to plot their protest and Israel was able to block them from entering the country. Now that it's happened once however, I don't expect it to work again, at least not as well. Next time Israel (or whatever country) will need actual confirmation from Facebook/etc. to get real identities, and they might not be able to get that information.
And they didn't put them on any kind of general no-fly list, they denied them entry to Israel, which is well within Israel's rights. (They don't have to let anyone enter if they don't want to.) If they'd put them on a general terrorist no-fly list that affected their travel to other countries it would be outrageous, but they didn't do that, so no, it's not more outrageous. Using someone else's name would have had no impact on that person unless that person was also planning to travel to Israel.
Go ahead. Continue to ignore the ease of which I can now use your name online to falsely incriminate you... If you are not outraged now, then maybe you will be when you can't fly, ride a train, get a driver's license, or vote because of something I said or did using your name?
I'd be royally pissed off at you, more so than whatever I was blocked from. But that's not the issue here, the block was very specific (only preventing people from being allowed to enter Israel), not blocking them from traveling in any other way. Sure the potential is there, but so far it's not happening. I also don't see many other countries trying this and as I noted above, it's not something that's likely to work effectively a second time.
I can't say I like this kind of thing, but Israel is within their rights to block entry to anyone they want, and there's no indication Facebook provided any non-public information to Israel in this case. So as much as I don't like it personally, nothing really shady's going on, and one would hope people using false names for something like this would pick a name of someone who was unlikely to be impacted. That is, make sure to use a name of someone unlikely to be traveling to Israel as their cover name for discussing a protest in Israel.
