Some people will keep their correct identity in the social media but they take care of their postings in such a way that nobody knows about their actual nature. Some good people may appear as bad and some bad people may appear as good. If we assess them by this our efforts will get in vain.

But for any other activity you should do this exercise. So be cautious and don't go for assessing people basing on their social media actions.
