block users

I just wanted to post here to see if there is there any way that we can get an option to block users. While 99% of the people are Imgur are awesome, there's always those few people in every group that are only there to try to make everyone else miserable. A perfect example of this is someone who made a new account today with the sole purpose of mimicking and annoying another user (as is stated in their profile comment). And now anyone who suggests that he calms down becomes a focus for his childishness as he adds their names to his profile "rant" and goes out of his way to find and reply to comments made by those people. Having my notifications spammed by someone screaming in all caps lock isn't my idea of fun.
