For me, I won't block anyone on my Wechat account (A China social media). I know there are some bully on the contacts, but I know I have to face something that I don't like to in really life. In one word, I won't avoid anything.
What's your opinions?
It does not make sense to block anyone so far as I am concerned because I am convince ignorance is the most useful power to defeat harassment, insult or bully, but that is only my personal perspective.
