Auto Contribute Bug

Not exactly sure how or when but sometime in the week my auto contribute was turned on & ended up sending 10 BAT without my knowledge & I defiantly didn’t turn the feature on. I’m not too bothered but I’ve only earned about 8 BAT this month so kinda feels like a waste of time, I doubt I can get the BAT back but want to at least let this be known even though I have no idea what caused it to turn on in the first place.
