Three days ago, I start receiving random direct messages with colourful languages. At first, I choose to ignore and ignore that member. But, they keep coming back again and again. Just a few minutes ago before I write this post, I see those same spams again. I am confident that my account is not hacked yet and the password is not leaked. It is very distracting because direct message count will remain there forever unless I take actions. I want to get rid of them once and for all, or at least, for a few months. What could I do?
