I am all for reporting people for shit behavior. I totally am. But there are ways to deal with it on the player's end that can, and in my opinion, should be done first. Outside of extreme cases, reporting a person to staff should only be done as a last resort, in my opinion. So-in-so is doing something you consider harassment? Block them via client after telling them to leave you alone and that you'll be blocking them, logging you doing so. If they circumvent it or find other ways to bother you... then report them. Provide the log of you asking them to leave you alone and notifying you'll be blocking them along with the other evidence.
ETA: Staff usually has enough on their plates as it is. FFS, please stop adding to their work load. Do what you can on your end first before involving them.
