Sad, I get that it might be to small a case to actually deal with, but most cases will be. Only in aggregate will complaints as your ever get anywhere.
On a positive note, I have noticed that deleting accounts have become much easier after the introduction of the GDPR, and more and more I see tracking opt-in/out forms where opt-out is just as easy as opt-in. So something is working.
This is actually a really good idea. A Trust Pilot type of site which is owned by a non profit or some such with no monetary interest in contrast to TP where GDPR issues toward companies can be created, shared on social media and executed automatically when a number of people agreed to complain about the same issue.
