I cannot stress enough how important it is for you all to take the 5-10 minutes it takes to file this complaint.
If the Irish DPC receives only my complaint they will likely not pay it any attention for at least 18 months if at all - but if they receive 10 000 complaints it will seriously eat into their budget (it costs money to handle complaints) and will "motivate" them to act much faster.
If they receive 100 000 complaints - YouTube will be forced to stop this very quickly indeed.
