Managing Customer Departures and Data Privacy in Communities

how are you dealing w/ customers who decide to leave the community? do you keep their info on tightknit?

can individual members opt out of public posts (if not, I assume it's within your terms/PP that their info can be shared)

any issues w/ internal teams in terms of data access (i.e passing on PII from your customer base to another platform) that you had to go through?
