If you have a person who writes a trolling post out of anger, the event of them getting a PM that their post was deleted triggers the anger again. This can lead to more engagement.
On the other hand, just greying out the post doesn’t produce engagement with the topic in the same strength.
Given that we don’t have that many angry trolls at the moment, I however don’t think this is an important issue.
