To get back the 1000 STR, you will need to allow Stellar to interact with your Facebook account
It was unable to do so when I tried. How motivated should I be to give this any more of my attention?
Also, why does Stellar want access to my Facebook account? Is there any danger of it spamming everyone on my friends list with ads for Stellar?

I am guessing it wants your information. Personal data is valuable -- Stellar is willing to give you some of its funny money to acquire yours.

MIRI are currently holding a donation-matching challenge, until Friday 15th August. You can donate and track its progress by going to the Donations page.
Also, to quote the MIRI Facebook page:
Registering for Stellar requires just a username and password, no e-mail or verification required. To get the free Stellar, you have to have Facebook Platform turned on (see the first setting on this page) and allow the Stellar App to temporarily integrate with your account. Send 1000 STR to 'miri' or their address (gHhshpzDcfRsie2qxjjHqrsTRe3JSCaUeN), and you will get back the 1000 STR. Once you receive back the 1000 STR, you can then remove the Stellar app like any other in your Facebook settings.
Edit: The promotion seems to have been reduced. See these two comments.
Edit2: The promotion seems more-or-less gone now; consider the part of this post about Stellar irrelevant.
I did this and it took me maybe three minutes (including time to take notes). The Stellar website is self-explanatory. If you encounter difficulties at any point in the process, or if I've forgotten some part of the process, feel free to comment on this post to that effect.
To track follow-up on threads like this: If you donate because of this thread, please indicate that in this comment (you can do so anonymously there if you prefer), and feel free to state that you have donated as a reply to that comment.
(If you're thinking free cryptocurrency is too good to be true, and wondering what the founders get out of it: My understanding is the reason this works is that early investment in a cryptocurrency bolsters it, so that giving away some for free at the start is actually a smart thing to do at first for the founders. No gimmicks or tricks about it asking for card details or anything dodgy like that.)
