Looks like the ban on blocking over at #Twitter isn't very likely to happen - at least not for long:
Then again, it seems nonspecific as to who must be able to block abusers. Is it enough if #Twitter itself has the only blocking ability? Or must users be able to block?
I went to the help section of Play store and asked specifically who has to be able to block abusers.. Waiting for them to get back to me.
