Several people already have told you what to do and a GM even told you what to do in your previous thread that got locked down. Closing Out Thread
I gave you some advice too and just put them on ignore and follow what people have told you. Others told you to take some of the ones in trade off ignore and right click report for spam those so you can place his toons on ignore. If this person is causing you this much distress you need to do what is being suggested. Coming to the forums and making new threads just doesn’t help matters any. Providing all information to a gm that you can in 1 to several tickets and placing every single one on ignore and not engaging with them will help get it to stop.
Have you heard the phrase, “Someone got your goat?” meaning they are getting you so riled up and mad that you lost your temper sanity (your goat in the phrase). I’ve had similar happen to me, and not feeding into it makes it stop. Reason being is they no longer find getting your “goat” entertaining. Doing what you’re doing now if the other person is reading it is feeding into whatever they are doing to harrass you because it’s working to make you upset. Place them on ignore, do what others have suggested, and move forward with reporting and tickets.
Everyone in this thread thus far has gave 100% solid advice already so I won’t expand upon that regarding addons and the like.
