One more step, a lot more security.
Or at the very least make it easier to find things that you have liked ( I am speaking without actually going to look if its easy to find it... I just remember it was very hard to find the last time I tried )
I think the solution they'll end up implementing (if they do anything) is an "I didn't Like this" link that users can click to report false clicks. If a company gets more than x% of those they get taken down. It's not a legit solution but should be fairly effective.
The solution to this problem is to not mislead users by embedding one domain's content within another site in the first place.
