How to report harassment
The in game method requires an ally code, which I don't have.
We have a guy in our arena shard, that I reported a year or so ago. He seemed to disappear, but unclear if anything was done. He would endlessly harass players. Focus on single players just to drop them one place or max drop, it didn't matter, would just repeatedly focus attacks on single players without any reason. He would change his in game name to match another player and then copy their profile pic. He returned today with the same tactics of copying a player name and portrait, but went one step further by starting a guild with the same guild name as the player he copied. He then dropped that guild and created one titled "Your worst nightmare is back EdSolo" which is my username here and in game. I have a screenshot of it. He has now changed back to Mol Eliza, which, even though a common default name, was what he used previously to harass another player who used the Mol Eliza name.
Essentially this guy has no life and will spend any amount of crystals on refreshes to target players. While I doubt there is anything to be done about endless attacks, the changing names, imitating other players, and calling me out specifically I think should constitute harassment. I thought this guy had quit since it had been over a year, but he is now back and back to his old ways. I'm fairly certain he purchased the account from someone else years ago because he started as an older username before doing the copy name thing.
