This is a very common complaint after a test administration and is why I do my retake tests at Starbucks. I put my earbuds in to hear the proctor app, but it's still very distractions. Prepare for the worst, hope for the best.
I would file a complaint. The LSAT is only legit if the integrity of the test is maintained. Even if I thought I did ok, I would file a complaint. It's the right thing to do.
Sorry to hear about this - I would be frustrated too. You can go ahead and file the complaint, but don't expect anything more than LSAC giving you the option to cancel your test score.
Wait until they release the scores and if you did poorly then file a complaint. This isn't the time for some false sense of nobility as you might hurt other people that took the test that day and not just yourself if you were to complain now.
if you file a complaint you have the option to cancel your score (either way it MAY be delayed) and if you decide to cancel you will most likely be given a waiver to retake the LSAT for free (can't remember if you still get a count towards your 3)
When in doubt, always disclose. This incident is not a ... out and you didn't disclose it in the first place ... you don't need to disclose but generally schools will appreciate ...
Also, is it possible to randomly find it on a Google search? If so I would disclose everywhere. Just because a background check might not be international doesn't mean that this couldn't easily turn up elsewhere given the nature of the Internet.
