Being Spammed
You need only report and block. Posting a picture or even making a thread would be against forum rules.
Report, and ArenaNet will do the rest.
Hello,
Like Inculpatus Cedo stated in her post, if you feel a player is abusive in-game, please report them using the in-game ticketing system so our Customer Support team can properly investigate the issue and take any appropriate action.
Indeed, discussions of gold selling, in-game abuse, hacking, exploiting, and the like are not allowed on the forums.
Thank you for your understanding.
