The largest tech website and discussion platform in The Netherlands, tweakers.net, uses a similar approach. They restrict the time a message can be edited, and after the timer expires you can't delete it anymore. They do allow you to delete your account but your messages will still remain with a numeric "Anonymous User #1234" identifier. Such an approach is justified using the exceptions under Article 17.3.A, which states that "[The right to erasure] shall not apply to the extent that processing is necessary for exercising the right of freedom of expression and information". They argue that deleting comments has a significant negative impact on the discussion as a whole, and it would be a violation of the other users' freedom of expression. I'm not sure I completely agree with this interpretation, but as far as I am aware it hasn't been tested in court yet so who knows.
