Might be worth tossing a suggestion over in Existing Game Content for the report flag to not be blocked by that interface while on the legacy UI. That area will have the content devs be able to see it and be able to properly adjust the legacy layout.
As for the suspected bot, that has to be reported in-game. There's not a way to report it on the forums since the forums don't record the information that an in-game report option does.
Simply disabling the legacy UI in the settings panel under miscellaneous settings at the bottom will let you be able to hit the report flag easier.Can I turn in a paper without citing all sources?
