User with 8,000+ posts requesting post deletion per GDRP

[BlueGreen91]

Hi everyone, I hope some of you can help. Our forum recently received a post deletion request citing GDPR, and the user has 8,000 posts. It is difficult to remove this many posts and having to do a query to remove them all will definitely cause the server to crash, so we will probably have to take the website offline to do it.

Am I correct in assuming I can delete this user's account and anonymise their posts? Or would post deletion still be required to comply with GDPR?
