Do you use the mobile web version? I did exactly that when using the web version on iOS (chrome specifically). Scrolling down the page ended up with me accidentally hitting like on a number of various posts the feed.
I was using the desktop version on Opera on an Android tablet at that time. I've never accidentally opened links while scrolling before, so I highly doubt that is what caused it.
Even so, how would that cause me to "like" it, but not "follow" it (which is a default function of "liking" a page)?
