To begin with, I've already read the following topics:
- Facebook Like without Confirm?
- Facebook Like button shows the "Confirm" link, but still cannot Like after confirming
Including this topic:
There are at least 25 apps hosted under dev.anuary.com host, sub domain of anuary.com. Neither of them ask for "like" action to be confirmed.
Worth mentioning, is that there is another website ( http://sinonimai.lt ) hosted on the same host, that had a fan base of 10 000+ people and was recently disabled by Facebook. I didn't manage to contact Facebook regarding either of the issues, therefore I simply took off the like-box from the latter website. Hopefully, temporarily.
The most annoying of all, is that even if you confirm the "like" action, "like" doesn't get submitted. I've tried on multiple friend accounts, different browsers (possible bug to report?).
I've ignored it for over a month. But it doesn't go away.
There are no hidden overlays, no bouding elements or anything that'd be considered unusual placement of the "like" button element. The website and the button itself has been placed very recently. The open-graph tags are in place and changing app ID doesn't change the behavior.

However, the page content is loaded dynamically. What Facebook parser sees is pretty much an empty page.
Can this be an issue?
Unfortunately, I think you are running into a recent Facebook change/design decision. Here are a couple bug reports discussing this issue:
Use the Facebook Debug tool to see what content is on the page. http://developers.facebook.com/tools/debug
It shows you what Facebook sees when it scrapes the page. It could help in identifying what the underlying issue is.
With regards to liking / unliking content multiple times, Facebook has some automatic features that prevent likes from showing up on Facebook, or indeed showing the 'Confirm' link you are seeing. This is mainly to combat click-jacking as this is a common problem with the Like button.
The issue which I faced was when I had my page in production server and then when I was making modifications on my development/testing server it came up with 'confirm'. So it seems to think that I am trying to spam 'like' through different pages to achieve a higher ranking but all I am doing is trying to test my changes on a different server before uploading them to production server. I am not comfortable with making changes straight into production as it could blow up in my face with buggy code or an undesired layout.
