“We have received many reports this season about match manipulation both here on the forums and via in-game reports. Our investigation revealed that a few players were sharing a handful of accounts, which is clearly against our user agreement.
While the investigation into this is still ongoing, at this time we have enough evidence to take action. As a result, we’ve decided to give dishonor to the offending accounts for the rest of the season.”
Most recently, ArenaNet says it’s “identified additional accounts of players who were involved in account sharing and match manipulation” — they’re getting dishonor too. “Our investigation is still underway, so additional action may be taken later, should we determine it appropriate,” writes the studio.
