My guild is a active raiding guild with many active members, completing Ulduar/TOC/etc. A level 1 has been giving us hundreds of flasks/mats/gold for repairs, across the span of a month. We're not sure who recruited him, and he is at lowest rank. He's on shortly every other day or so, only long enough to deposit - he doesn't reply to whispers. We don't have proof but we are pretty sure it belongs to a botter. It probably belong to someone in the guild, but we are keeping it under the radar at the moment and don't want to ask everyone. Those of us in charge don't have an issue with it, but are we at risk for any punishment for using these mats and gold? The fact that we think its a bot has not been mentioned in-game ever.
If the bot is discovered/reported are we liable for using the materials/gold?
