Account was suspended about 10 months ago (for no reason given). I sent Heroku, Salesforce, their data protection officers emails asking them to remove my account, databases, codes, everything on it.
I kept receiving notifications that an active account would receive. And their DPO lied to me that they have closed the account.
Another US company doing that is not really a coincidence.
They were going downhill since Salesforce takeover.
