There are lots of Elder rift farming bots in my server (Town Portal/Hell3). They are easy to spot because they all have the same characteristics:
Character level around 30
Short random character name
They always play 10 eternal legendary crests at a time
They always exit the rift from portal as soon as it starts
I was wondering why there are so many and if Blizzard is doing something to keep the game fair. Is it worth reporting those accounts or just a waste of time?
