 Concerns have been raised about online "stalking" or "creeping" of people on social media, which means looking at the person's "timeline, status updates, tweets, and online bios" to find information about them and their activities.While social media creeping is common, it is considered to be poor form to admit to a new acquaintance or new date that you have looked through his or her social media posts, particularly older posts, as this will indicate that you were going through their old history.A sub-category of creeping is creeping ex-partners' social media posts after a breakup to investigate if there is a new partner or new dating; this can lead to preoccupation with the ex, rumination and negative feelings, all of which postpone recovery and increase feelings of loss.
